The dipole antenna of a radar altimeter of 1947. A radar altimeter (RA), also called a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft.
AN/MPQ-35 PAR (Pulse Acquisition Radar) high/medium-altitude threat detection radar for MIM-23 Hawk surface-to-air missile system. AN/MPQ-43 mobile High Power Acquisition Radar (HIPAR) for Nike ADM. AN/MPQ-64 Sentinel; AN/MSQ-1 Close Support Control Set for Radar Bomb Scoring (RBS) AN/MSQ-1A used for Matador Automatic Radar Control
1L222 Avtobaza exhibited at the 2014 Engineering Technologies International Forum [] in Zhukovsky, Russia.. Kvant 1L222 Avtobaza is an ELINT system designed to detect side looking airborne radars, air-to-ground fire-control radars and low-altitude flight control radars, as well as to provide intelligence data for the 1L125M APUR.
A Royal Air Force Boeing E-3 Sentry over North Yorkshire. An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack ...
Maritime Modes is planned to be integrated with the RQ-4B's existing MP-RTIP radar to detect and produce synthetic aperture radar imagery of ground vehicles. [76] In November 2015, Northrop Grumman selected the Garmin International GSX 70 weather radar to be installed on Air Force Global Hawks. The GSX 70 is designed to provide operators with ...

The Northrop Grumman RQ-4 Global Hawk UAV is used by the US Air Force for surveillance and security. It carries a radar, optical, and infrared imagers; and is able to transmit its data in realtime. [18] Real-time monitoring An area could be monitored for flood detection, seismic monitoring, remote sensing and disaster management. [19]
TSR-2 XR220 at RAF Museum Cosford, 2002. Ferranti developed the first terrain-following radar specifically for the TSR-2. Terrain-following radar (TFR) is a military aerospace technology that allows a very-low-flying aircraft to automatically maintain a relatively constant altitude above ground level and therefore make detection by enemy radar more difficult.
