In 2019, the U.S. Army selected Lockheed Martin to develop the active electronically scanned array (AESA) variant of the radar in a $281 million contract. [5] The Sentinel A4 is a complete redesign of the sensor that uses digital processing and solid-state antenna modules based on gallium nitride (GAN) transmitters.
Development of the Hawk missile system began in 1952, when the United States Army began studies into a medium-range semi-active radar homing surface-to-air missile. In July 1954 development contracts were awarded to Northrop for the launcher, radars and fire control systems, while Raytheon was awarded the contract for the missile.

Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect , which causes the received signal to have a different frequency from the transmitted signal ...
M734 fuze cross section Amplifier (top) and oscillator. The M734 multi-option fuze [1] is a rangefinder and collision detection system used on 60 mm, 81 mm, and 120 mm mortar shells as a trigger to detonate the shells at the most damaging heights of burst when combating four types of battlefield threats:
The system is a "weapon-locating radar", designed to detect and track incoming mortar, artillery and rocket fire to determine the point of origin for counter-battery fire. It is currently in service at battalion and higher levels in the United States Army , United States Marine Corps , Australian Army , Portuguese Army , Turkish Army , and the ...
The Radar Set AN/MPQ-4 was a US Army counter-battery radar primarily used to find the location of enemy mortars and larger artillery in a secondary role. Built by General Electric, it first entered service in 1958, replacing the earlier and much simpler AN/MPQ-10. The MPQ-4 could determine the location of an enemy mortar in as little as 20 ...
It is currently in service at brigade and higher levels in the United States Army and by other countries. The radar is trailer-mounted and towed by a 2 + 1 ⁄ 3-short-ton (2,100 kg) truck. A typical AN/TPQ-37 system consists of the Antenna-Transceiver Group, Command Shelter and 60 kW Generator.
