NEBO-SV (1L13-3),
Mobile 2-D VHF Band Radar System
The IL13-3 NEBO-SV Radar is designed for mobile air defence (AD) and air traffic control.
The IL13-3 Radar System is the latest member of the "NITEL" JSC family of Radars being manufactured for 50 years and in service around the world.
The system''s phased array antenna is of folding design and includes antenna rotation and lifting drives.
The Radar system is mounted on URAL-4320 Cross-Country Vehicles allowing deployment of the Radar system within a short time on unprepared sites.
The phased array antenna is connected to transceiving equipment with flexible cables for optimum positioning of Radar cabins on the site.
The NEBO-SV Radar can be an integral part of automated AD units or perform autonomous air surveillance missions.
The Radar can be optionally equipped with remote plan position indicators (PPIs) enabling control and monitoring of the Radar performance from a distance of 500 meters (Art. IL13-3-1). This substantially enhances survivability of the Radar system operating within AD units and permits to increase the number of air targets being autonomously tracked.
A Radar environmental simulator is available for training of the personnel.
Power supply of the Radar system is provided by the diesel power station organic to the Radar system, or the mains.
Data link with AD centers is provided with the Radar built-in air target data transmission equipment and radio sets operating in telegraph and telephone modes.
Main Features
Superior Detection Performance
Superior long-range detection of any air targets including those manufactured according to STEALTH technology is achieved due to clever integration of advanced factors, such as operation in metric wave band of radiated frequencies, repositioning of antenna radiation pattern in elevation, state-of-the-art components, compression of received signals, high resolution and power potential, automatic local rejection of active and passive jamming, efficient rejection of echo-signals from underlying surface, immunity from meteorological clutter, rejection of low-velocity targets, high accuracy coordinates determination, automatic gain control of receiving channels and constant false-alarm rate processing.
High Mobility and Operation from Unprepared Sites
The NEBO-SV Radar antennas and equipment are mounted on trucks and trailers allowing their deployment onto unprepared sites without any support means and weight lifting devices. Complete deployment of the Radar takes not more than 45 minutes. Independent power supply and high cross-country capacity of URAL triple-drive six-wheelers provide deployment of the Radar in hard-to-access areas and ensure freedom of selecting site.
High System Availability and Reliability
Built-in continuous automatic performance monitoring, fault finding and fault isolation equipment makes Radar system highly available and reduces the need for complicated test-and-measuring instruments and tools. Use of the state-of-the-art components as well as duplication of the Radar main systems combine to ensure entire system reliable operation within its service life, as well as easy maintenance and repairs.
Efficient Rejection of Natural and Man-Made Interference
The Radar incorporates efficient systems of:
- ground and meteorological clutter rejection,
- operator-programmed transmitter frequencies,
- automatic transmitter frequency agility (within 15 % of bandwidth) adaptive to environmental interference,
- programmable transmitter frequency agility in azimuth,
- rejection of ghost echoes received by side lobes under con***ions of excessive reflections to improve resolution in azimuth (Control of Side Lobes Blanking-CSLB),
- automatic rejection of active jamming received by side lobes and major lobe of Radar radiation pattern,
- constant false alarm rate level,
- MTI with low velocity target rejection.
Enhanced Radar Performance
The Radar onboard computer simultaneously processes 256 air targets displayed on the Radar indicators and support digital data interchange with automated AD control centers. Built-in autonomous IFF system interrogates air targets "Friend or Foe" and displays the data on PPIs''.
Interference direction finding system permits Radar operators to evaluate the environmental factor and take appropriate decisions.
A Radar environmental simulator is intended for training of personnel, evaluation of Radar performance and maintenance. Data are displayed on the PPIs in graphical and alphanumeric form.
High survivability of the Radar system and its crew is ensured by the air-con***ioning system; sensor-operated fire extinguishing system; NBC protection systems.

Nếu Mig-29SMT có thể đánh được tàng hình thì Su-27SKM và Su-30MK3 cũng có thể chứ
During the MAKS ''''''''97 Air Show, the President of the Russian Federation Boris Yeltsin stayed over half an hour, instead of the scheduled five minutes, in the pavilion of the MIG "MAPO." He was attracted by the latest updated version of the famous MiG-29SMT fighter. Impressively built President felt comfortable enough in the ****pit of the new aircraft to stay there for ten minutes asking the designers questions. Among other things he paid attention to the data that could be clearly seen on the two color liquid crystal displays despite the bright sunlight. Multifunctional control panels and an ergonomical combination of digital and needle indicators that pilots are accustomed to, make the
****pit especially comfortable to work in. From modernization to modernization the aircraft''''''''s "intellect" has been more and more distinctly revealed in its ****pit.
State-of-the-art avionics do not break down the stereotyped concepts of aircraft control mastered by pilots, but help them cope with the execution of an increased number of tasks by providing them with information in more agreeable way at the appropriate moment.
The President approved the course of activity adopted by the MIG "MAPO" headed by Anatoly Manuev to turn the MiG-29 fighter into a fifth-generation aircraft via step by step updates. Meanwhile, these improvements can be incorporated in earlier produced and currently operational aircraft. The company has built more than 1,300 aircraft. Over 300 of them are still operational abroad. What is most intriguing is that the United States also purchased MiG-29 aircraft. One can treat differently their explanation for purchasing 21 aircraft from Moldova: they claim that there was a danger that the aircraft would be delivered to Iran. In any case, this speaks volumes about the respect for the MiG-29 on the part of our principal competitor. The MiG-29 optimal aerodynamic configuration, developed on the concept of integrated aerodynamics and reliable structural strength, ensured its long service life. One interesting point is that during aerodynamic tests one of the fighter prototypes was placed entirely into a wind-tunnel - an extremely rare event.
The record of the sequence of updating the MiG-29 revealed that every subsequent modernization opened up new vistas for more sophisticated improvements. Initially it was developed as a light frontline fighter to gain air superiority and it has successfully performed this role.
Naturally, however, its creators did not sit back. The airborne computers were geared with more sophisticated software to mount new missiles and enhance their efficiency and introduce more reliable methods of guidance and radio-correction. They created MiG-29s that incorporated the complete spectrum of improvements achieved at that time. Radical improvements occurred in increased capacity of the internal fuel system and equipment compartments. A more sophisticated control system was installed that was especially effective at large angles of attack. Drop fuel tanks were also installed. Modified software made the radar more resistant to jamming and allowed it to use more effective algorithms for radio signal processing for target detection and lock-on. The RVV-AE medium-range missiles with active radar homing heads were also put into operation at that time. Further modifications made the MiG-29 a fully multirole aircraft. The MiG-29 was fitted with air-to-surface high-precision weapons, including the X-29T TV guided missile and X-31P missile with a radar homing head, KAB-500KR guided bombs, etc. The aircraft was also equipped with the in-flight refueling system specified by the Malaysian customer. The aircraft''''''''s wing structure was reinforced to increase combat payload to four tons. At the same time work was underway to improve the RD-33 engine and radically increase its reliability and service life. The adopted version was designated the MiG-29SM.
The latest is the MiG-29SMT version currently undergoing intensive tests. What are the main differences between this version and the MiG-29SM?
First and foremost, its increased operating range. The MiG-29 has been criticized for a short operating range compared with that of heavy fighters. However, the MiG-29 was developed as a frontline fighter never to be beaten in air combat. The aircraft combat capabilities were highly praised during NATO exercises.
Today, two MiG-29s from the GDR arsenal are constantly on combat duty in the German Air Force, although these aircraft are only predecessors of the MiG-29S. The small -size MiG-29 is harder to pinpoint visually or via radar contact than the F-15 fighter. The MiG-29 pilot will see the F-15 first. The F-15 constitutes a very attractive target for the RVV-AE missiles carried by the MiG-29 fighter. Our designers managed to accommodate ad***ional 1,000 liters of internal fuel without increasing the aircraft dimensions. This ad***ional amount of fuel is sufficient to enable the aircraft to cover another 500 km. In doing so, developers mounted air-intakes from the updated MiG-29M (actually it is a completely new aircraft also known in the press as MiG-33). Unfortunately, it was not put into the series production although it underwent practically all tests. The aircraft was designed to incorporate many units taken from the MiG-29, namely air-intakes and wings. The use of these air-intakes allowed developers to arrange 650 liters of internal fuel in wing leading-edge extensions and an integrated fuel tank arranged in a fuselage fairing to increase fuel capacity to 1,000 liters. Provision is also made for the use of three drop fuel tanks borrowed from three previous updates, which will increase the operating range two-fold. However, this is not the limit. In further updates it is possible to use wings from the MiG-29M to arrange ad***ional fuel and increase the number of suspension points for weapons.
In ad***ion to the new ****pit and most advanced avionics, the MiG-29SMT will be fitted with new
high-precision weapons, primarily the X-31A missile to defeat sea targets that is without equal abroad. The new updated airborne radar allows terrain cartography to increase the guidance efficiency.
A great deal mentioned above became possible thanks to the efforts made by Mikhail Korzhuev, Director General of Aviation Research and Production Complex, and investment support of MAPO Bank, headed at that time by Yevgeny Ananyev (now Director General of the Rosvoorouzhenie State Corporation). The principle of open design architecture followed by developers of the MiG-29 allows them to easily install Western avionics and armament. There are many interesting and promising engineering solutions to this effect.
The MiG-29SMT will continue to be updated, primarily to obtain increased maneuverability. Currently, a thrust-vectoring controlled engine is undergoing tests that will be soon installed on the aircraft. Naturally, all innovations developed by the MiG-29 designers cannot be disclosed due to military and commercial considerations. However, Valery Novikov, Senior Designer, and Mikhail Waldenberg, Designer General of the MIG "MAPO," are sure that the MiG-29 will be among the leading fifth-generation fighters in the first decade of the 21st century. THE MIKOYAN MIG-29SMT CERTIFIED BY THE RUSSIAN AIR FORCE
Valery Novikov, Chief Designer of the MiG Aircraft Research and Production Complex
The beginning of 1999 marked a portentous event: the MiG-29SMT was certificated by the Russian Air Force heralding the commencement of modernization of MiG-29 fighters that are currently in service with the air forces of Russia and other countries, as well as MiG-29SMT''''''''s series production. Delegations from many countries operating the MiG-29 and potential buyers have already acquainted themselves with the new aircraft. Several foreign pilots from these delegations made familiarization flights on the MiG-29SMT and gave it high marks.
The MiG-29 modernization program provided for:
longer range by increasing internal fuel capacity and incorporating flight refueling system and underwing drop tanks (for early-series aircraft which did not have these features);
principally new ****pit information and control panel which includes two large (6ax8a) full-color multifunctional liquid-crystal displays and a multifunctional control panel with a dedicated display. The introduction of displays required the re-arrangement of the instrument board and starboard console. In this configuration, the ****pit fully corresponds to the HOTAS (hands on throttle and stick) concept;
new open architecture of an onboard equipment complex with multiplex channels (corresponding to the MIL-1553B standard) and a central processor with PC-compatible software;
longer service life and on-con***ion maintenance;
multifunctional radar with air-to-surface modes;
enhanced stealth capability in radar frequency band;
new weapon systems;
new IFF, communications and navigation systems which meet the ICAO and/or NATO standards; more effective ECM systems; new flight data recorders and inter-aircraft data links.
The aircraft can be equipped with an optronic sight pod, a jamming station and GPS/GLONASS-based navigation systems. In ad***ion, a ground station for flight planning and data preparation can be supplied.
Part of the above-mentioned systems are either undergoing flight tests or have been installed on several MiG-29 fighters, or are organic to the equipment already certified for other types of aircraft. This provides an opportunity to offer each customer an affordable version which will meet his specific requirements. A batch of aircraft equipped to customer request can be produced within a short term.
Other projects under the modification program which require longer implementation time include:
modified engine with augmented thrust, thrust vector control and better fuel efficiency (with earlier linear dimensions and attachments retained to make the modified engine interchangeable with previously produced ones);
new wing consoles with four hardpoints on each, increased internal fuel capacity and larger area (the console''''''''s shape was flight-tested on a MiG-29K version);
more capable and reliable integrated fly-by-wire flight control systems.
All projects are based on a considerable technical expertise, while the modified engine and fly-by-wire flight control systems are being bench-tested.
Work is underway on all announced updates, as well as the development of several MiG-29SMT versions, such as:
the MiG-29UBT: a version of MiG-29UB combat trainer with increased internal fuel capacity; the flight refueling system; the ****pit and equipment architecture similar to that of the MiG-29SMT; an optional multifunctional radar able to control air-to-air medium-range missiles; and an array of air-to-surface guided weapons. The two-men crew can effectively control group missions and provide target designation for ground-based weapon systems and naval ships, as well as ensure the efficient employment of Ovod-type TV-guided missiles;
the MiG-29SMT can also be used as a reconnaissance platform carrying a variety of special-purpose reconnaissance pods;
large internal fuel capacity, two drop tanks and the UPAZ unified refueling pod are good prerequisites for a MiG-29 tanker version;
technology used on the MiG-29K fighter will help develop a MiG-29SMT deck version. These variants were displayed at major air shows: MAKS ''''''''97, ILA ''''''''98, and Farnborough ''''''''98. The MiG-29UBT made its debut at Farnborough last year.
In terms of combat capability, the modernized MiG-29 (MiG-29SMT) does not yield to the European fourth+ generation fighters (Eurofighter, Rafale, Gripen) and even outclasses them by some parameters. It should be noted that the modernized aircraft will use the existing technical maintenance infrastructure, flight and ground crews. Furthermore, MiG-29''''''''s modernization costs will not exceed 10 percent of the price tag of foreign analogs. Modernizing the existing MiG-29s and building new updated versions in compliance with a country''''''''s infrastructure are economically feasible and advantageous. This facilitates the coordination of offset programs and allows a customer to choose a requisite MiG-29''''''''s technical configuration via an integration of unified equipment standard for this type of aircraft.
The MAPO MIG and Nizhni Novgorod-based Sokol Aircraft Plant (MiG-29 manufacturers) and the MiG Aircraft Research and Production Complex (MiG-29 developer) guarantee operational service support for the aircraft and further enhancement of its combat capabilities during its full life cycle.

R-27 missiles

Theo tôi biết thì kế hoạch sx R-27AE (active homing radar) này đã bị hủy bỏ sau khi Nga bắt đầu phát triển R-77 và nhất là sau khi phát triển R-77M (RVV-AE-PD)
- R-27AE sử dụng 9B-1103M active radar seeker, loại seeker này chỉ có thể lock các mục tiêu có diện tích phản xạ radar (RCS - Radar Cross Section) là 5m2 ở khoảng cách 25km (loại upgraded có đường kính 200mm) và ở khoảng cách 40km (loại upgraded co đường kính 350mm). Ở khoảng cách gần hơn các loại seeker này có thể nhận và lock các mục tiêu có RCS = 3m2.
- RVV-AE (R-77) sử dụng 9B-1348E active radar seeker, loại seeker này chỉ có thể lock các mục tiêu có RCS=5m2 ở khoảng cách 16km (diameter = 200mm). Loại RVV-AE-PD hay R-77M (Povyshenoy Dalnosti - extended reach) lại sử dụng seeker 9B-1103M của R-27AE.
Do diện tích bức xạ radar của F-22A chỉ là 0.07 sq ft nhỏ hơn nhiều so với RCS mà hai loại AAM này cần để lock-on do vậy 2 thứ AAM này khó mà lock và hạ được F-22
R-37 cũng đòi hỏi RCS=3m2.
9B-1103M active radar seeker
9B-1348E active radar seeker

Bạn suy nghĩ vậy là đúng vì F-22 mạnh nhất là tàng hình-nhưng bây giờ là khó nhận dạng và càng khoảng cách gần thì càng dễ phát hiện hơn. Còn R-27 vẫ là vũ khí chủ yếu của Su và Mig-bây giờ. Ngoài các loại R-27 nói trên các bạn còn có thể gặp vài loại sau
R-27 P (passive radar )-200km
R-27EM ( inertial dùng để đánh trên biển- 3m cách mặt biển -dùng cho Su-33 )-170km
R-27ET tầm xa cải tiến của R-27T
R-27ER tầm xa cải tiến của R-27R
còn về RCS mà bạn nói là tương thích với khoảng cách mà tên lửa tự tìm mục tiêu.Nếu RCS nhỏ hơn thì tầm tự tìm mục tiêu sẽ gần hơn. Còn R-27AE là loại tên lửa có nhiều chế độ điều khiển , có hệ thống computer ( bộ vi sử lý ) có lập trình ( re-programming ) để điều khiển tên lửa nên Radar Seeker chỉ là đưa tín hiệu ban đầu ( Input ) sau đó computervà phần mềm sẽ xác định mục tiêu. Có lẽ mình sẽ đưa và bàn sau. Còn R-27AE dùng cho Su-32/34, Yak-140... như bạn thấy ảnh sau
