The Raytheon/RCA AN/SPG-62 is an I/J-Band fire control radar on Aeigis-class ships operates as a component of the MK-99 Fire Control System (FCS). FCS controls the continuous wave illuminating radar, providing a very high probability of kill. The Mk-99 Fire Control System also controls the target illumination for the terminal guidance of Ship Launched SM-2 Anti-Air Missiles.

The AN/SPS-52 is a United States Navy three-dimensional, long range air search radar that is capable of providing contact bearing, range and altitude. It was used on Brooke class frigates, Charles F. Adams class destroyers, Hatakaze class destroyers, Tarawa class amphibious assault ships, Wasp class amphibious assault ships, Galveston class cruisers, Providence class cruisers and other ships. It was replaced by the AN/SPS-48 on newer ships and ships that received upgrades. The antenna is mechanically rotated for azimuth but electronically scanned for elevation.

The SPS-52 Navy shipboard 3-D Air Search radar is a very long range search radar with medium detection probability. The AN/SPS-52C can detect air targets at ranges in excess of 200nm. Being a 3 Dimensional Radar, it provides range, bearing and height information to the combat system. The planar array antenna employs frequency scanning to steer the radar beam and is capable of providing altitude on targets in excess of 100,000 feet. The Radar feeds this data into the ship''''s Integrated Automated Detection and Tracking system (IADT) AN/SYS-1, which provides targeting data for the ship''''s fire control system. AN/SYS-1 also presents this information on a Multi Functional Display and interfaces with the Naval Combat Data System computer to exchange track information.
The radar has a number of different modes which allow operators to select the best picture based on environmental con***ions. As frequency is varied, the radar''''s beam axis changes, and scanning can be accomplished in one axis (either elevation or azimuth). Variation in frequency tends to make this radars more resistant to jamming than if operated at a fixed frequency, and it also provides a solution to the blind speed problem in MTI systems. Frequency scanning does impose some limitations in that a large portion of the available frequency band is used for scanning rather than to optimize resolution of targets. Ad***ionally, this imposes the requirement that the receiver bandwidth be extremely wide or that the

Radar SPY 1D
The heart of the AEGIS systems is an advanced, automatic detect and track, multifunctional phased-array radar, the AN/SPY-1. This high-powered (4 MW) radar is able to perform search, track and missile guidance functions simultaneously with a capability of over 100 targets. The AN/SPY-l radar system is the primary air and surface radar for the Aegis Combat System installed in the Ticonderoga (CG-47) and Arleigh Burke (DDG-51)-class warships. It is a multi-function phased-array radar capable of search, automatic detection, transition to track, tracking of air and surface targets, and missile engagement support.
A conventional, mechanically-rotating radar "sees" a target when the radar beam strikes that target once during each 360 degree rotation of the antenna. A separate tracking radar is then required to engage each target. By contrast, the computer-controlled AN/SPY-1A Phased Array Radar of the AEGIS system brings these functions together within one system. The phased array can concentrate energy where it is needed. The operator can boost the range and resolution in a particular direction without blinding the ship to threats from another side. The four fixed arrays of "SPY" send out beams of electromagnetic energy in all directions simultaneously, continuously providing a search and tracking capability for hundreds of target at the same time.
The unique SPY-1 multi-function phased array radar system replaces numerous conventional independent sensors and is designed for the most challenging environments and missions, including long-range volume search, fire control-quality tracking and ballistic missile defense. SPY-1''s S-band frequency range permits optimum performance in all-weather operations and the ability to perform all major radar functions while simultaneously providing proven S-band mid-course guidance for semi-active missiles, such as the Evolved Sea Sparrow Missile, SM-2 and SM-3.

The AN/SPY-1 is a US naval radar system manufactured by Lockheed Martin. The array is a passive electronically scanned system and is a key component of the Aegis combat system. The system is computer controlled, using four complementary antennae in order to provide full 360 degree coverage. The system was first installed in 1973 on the USS Norton Sound (AVM-1) and entered active service in 1983 as the SPY-1A on USS Ticonderoga. The â?"1A was installed on ships up to CG-58, with the â?"1B upgrade first installed on Princeton in 1986. The upgraded â?"1B(V) was retrofitted to existing ships from CG-59 up to the last, CG-73.
The SPY-1D was first installed on Arleigh Burke in 1991. It is a variant of the â?"1B to fit the Arleigh Burke class. The â?"1D(V), the Littoral Warfare Radar, was an upgrade introduced in 1998 for high clutter near-coast operations, an area in which the earlier "blue water" systems were especially weak.
The SPY-1F is a smaller version of the 1D designed to fit frigates. It is not used by the US Navy but has been exported to Norway. The origin of the SPY-1F can be traced back to the Frigate Array Radar System (FARS) proposed to the German Navy in the 1980s.
The SPY-1K is the smallest version of the radar currently offered, based on the same architecture as the 1D and 1F. It is intended for use on very small vessels such as corvettes, where even the SPY-1F would be too large. As of 2007, none are in service, although the radar is incorporated into the design of the yet-unbuilt AFCON Corvette.

RaDar TACAN
The text that follows in this section is taken from "The Services Textbook of Radio, Volume 7, Radiolocation Techniques" by Brig. J. D. Haigh, O.B.E., M.A., M.I.E.E., E***ed by the staff of "Wireless World", H.M.S.O., London, 1960 pages 50 - 52. This volume was known to the British armed forces as Admiralty B.R.600(7), War Office 10224(7) and Air Ministry A.P.3214(7).
"Tacan" stands for "Tactical Air Navigation" and is a system which, working in the u.h.f. band, between 962 and 1,214 Mc/s, gives to a pilot continuous information as to his range and bearing from a beacon. The airborne equipment consists of an interrogating transmitter and a receiver which includes suitable demodulating circuits to enable the information contained in the beacon''''s response to be extracted. The ground equipment consists of a beacon provided with a rotating aerial system. In the absence of interrogating signals the beacon transmits a series of random pulses together with groups of marker or reference pulses which are locked to the aerial rotation. Bearing information can be obtained without interrogation since the beacon is continuously transmitting.
