AN/SPS-12 is a completely improved version based on SPS-6C. The antenna measures 17 ft (5.2 m) x 6 ft (1.8 m), weighs 550 lb (250 kg), and has a PRF of 300 to 600 pps. The radar coverage was similar to the AN/SPS-6B. In addition, it could be operated in an environment with a wind speed of up to 70 kn (36 m / s).
The AN/TPY-4, formerly known as the TPY-X, is a ground-based, active electronically scanned array, L-band, multi-function long-range 3D radar for air defense surveillance, built by Lockheed Martin. [2] It is a radar capable of multi-mission operation, and perform simultaneously the following work: air surveillance; low profile UAS detection
The ALQ-218 is mainly featured aboard the U.S. Navy's Boeing EA-18G Growler aircraft, [3] [4] which has replaced the EA-6B Prowler in the U.S. Navy. [5] The ALQ-218 was previously on the Grumman EA-6B Prowler, which the Improved Capability III ALQ-218 was modified and integrated into the EA-18G's Airborne Electronic Attack (AEA) system. [6]
The AN/ALQ-99 system on EA-6B Prowler Aircraft. The EA-6B in the foreground carries 3 under-wing jamming pods for transmitting and a single fixed pod on its tail for receiving. The ALQ-99 is an airborne integrated jamming system designed and manufactured by EDO Corporation. Receiver equipment and antennas are mounted in a fin-tip pod while ...
SPY-6 is intended as a scalable system, with each sensor array assembled from Radar Modular Assemblies (RMA), self-contained radar modules. [14] The Arleigh Burke deckhouse can only accommodate a 4.3 m (14 ft) version, but the USN claims they need a radar of 6.1 m (20 ft) or more to meet future ballistic missile threats. [8]
Diagram of AN/SPY-3 vertical electronic pencil beam radar conex projections. X band functionality (8 to 12 GHz frequency range) is optimal for minimizing low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination, and the target illumination for SM-2 and Evolved Sea Sparrow Missiles (ESSM).
The size of the antenna of SPY-1F is reduced from the original 12 ft (4 m) with 4,350 elements to 8 ft (2.4 m) with 1,856 elements, and the range is 54% of the SPY-1D. [5]: 316–317 It is not used by the U.S. Navy, although there were proposals to retrofit Freedom-class littoral combat ships.
The radar is designed with high resistance to electronic countermeasures (ECM) and anti-radiation missiles (ARM). [ 1 ] The system automatically acquires, tracks, classifies , identifies and reports high- and low-altitude targets, including cruise missiles , unmanned aerial vehicles , and both rotary- and fixed-wing aircraft .
