The AGM-88 HARM is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments.
The Raytheon Company was a major U.S. defense contractor and industrial corporation with manufacturing concentrations in weapons and military and commercial electronics. Founded in 1922, it merged in 2020 with United Technologies Corporation to form Raytheon Technologies, which changed its name to RTX Corporation in July 2023.
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR).
A counter-battery radar or weapon tracking radar is a radar system that detects artillery projectiles fired by one or more guns, howitzers, mortars or rocket launchers and, from their trajectories, locates the position on the ground of the weapon that fired it. Such radars are a subclass of the wider class of target acquisition radars.
The AN/MPQ-64 Sentinel is an X-band electronically steered pulse-Doppler 3D radar system used to alert and cue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. It is currently produced by Raytheon Missiles & Defense.
NASAMS is a short- to medium-range ground-based air defense system developed by Kongsberg Defence & Aerospace (KDA) and RTX Corporation. The system defends against unmanned aerial vehicles (UAVs), helicopters, cruise missiles, unmanned combat aerial vehicles (UCAVs), and fixed wing aircraft, firing any of a wide range of existing missiles.
A passive electronically scanned array (PESA), also known as passive phased array, is an antenna in which the beam of radio waves can be electronically steered to point in different directions, in which all the antenna elements are connected to a single transmitter and/or receiver. The largest use of phased arrays is in radars. Most phased array radars in the world are PESA. The civilian microwave landing system uses PESA transmit-only arrays.
Hughes AN/TPQ-37 Firefinder Weapon Locating System is a mobile radar system developed in the late 1970s by Hughes Aircraft Company, achieving Initial Operational Capability in 1980 and full deployment in 1984. Currently manufactured by ThalesRaytheonSystems, the system is a long-range version of "weapon-locating radar", designed to detect and track incoming artillery and rocket fire to determine the point of origin for counter-battery fire. 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.
The SLC-2 Radar is a Chinese active electronically scanned array counter-battery radar designed to locate hostile artillery, rocket and ground-to-ground missile launchers immediately after firing, and to support friendly artillery by guiding counter-battery fire.
The Type 704 is a counter-battery radar designed to accurately locate the hostile artillery, rocket and ground-to-ground missile launcher immediately after the firing of enemy, and support friendly artillery by providing guidance of counter fire. Built by NORINCO, it was first displayed publicly in 1988's ASIADEX defence show.
ARTHUR is a counter-battery radar system originally developed jointly for and in close co-operation with the Norwegian and Swedish armed forces by Ericsson Microwave Systems in both Sweden and Norway. It is also used by the British Army, under the designation TAIPAN.
Radar MASINT is a subdiscipline of measurement and signature intelligence (MASINT) and refers to intelligence gathering activities that bring together disparate elements that do not fit within the definitions of signals intelligence (SIGINT), imagery intelligence (IMINT), or human intelligence (HUMINT).
The Swathi weapon locating radar is a mobile artillery-locating, phased array radar developed by India. This counter-battery radar is designed to detect and track incoming artillery and rocket fire to determine the point of origin for counter-battery fire.
AN/TPQ-53 Quick Reaction Capability Radar is a mobile active electronically scanned array counter-battery radar system manufactured by Lockheed Martin.
The AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) is the United States Marine Corps next-generation Air Surveillance/Air Defense and Air Traffic Control (ATC) Radar. The mobile active electronically scanned array radar system is being developed by Northrop Grumman and was expected to reach initial operating capability in August 2016.
Aistyonok is a portable counter-battery radar system developed and produced by the state-owned Almaz-Antey corporation for the Russian Armed Forces.
Zoopark-1 1L219 is a counter-battery radar system developed by Almaz-Antey for the Soviet Armed Forces. It is a mobile active electronically scanned array radar for the purpose of enemy field-artillery acquisition. The system can detect mortar shells at a distance of up to 20 kilometers, up to 30 kilometers for artillery shells and up to 50 kilometers for ground-to-air rockets, determining location of origin of a fire. Moving ground targets can be detected at a distance of up to 40 kilometers. It reached initial operating status in 1989.
COBRA COunter Battery RAdar is a Counter-battery radar system developed jointly by Thales, Airbus Defence and Space and Lockheed Martin for the French, British and German Armed Forces. It is a mobile Active electronically scanned array 3D radar based on a wheeled chassis for the purpose of enemy field artillery acquisition.
The Centurion C-RAM, also called the Land Phalanx Weapon System (LPWS), is an American Counter-Rocket, Artillery, and Mortar (C-RAM) air defense artillery system. The system was developed in 2004, during and after the Iraq War identified a weakness in ground-based anti-projectile artillery. The system is produced by Northrop Grumman, Raytheon, and Oshkosh Corporation.
