    This is an incomplete list of ground-based radars operated by the United States Marine Corps since the service first started utilizing radars in 1940. [1] The Marine Corps' has used ground-based radars for anti-aircraft artillery fire control, long range early warning, Ground-controlled interception (GCI), ground directed bombing, counter-battery radar, short-range cueing for man-portable air ...

  3. Collision avoidance in transportation - Wikipedia

    en.wikipedia.org/wiki/Collision_avoidance_in...

    A radio detection and ranging (radar) sensor transmits a radio signal which bounces back to the radar when it encounters an object. Depending on the time it took for the signal to bounce back, the distance between the object and the radar is calculated. Radar systems have good resistance to weather conditions.

  4. Terrain-following radar - Wikipedia

    en.wikipedia.org/wiki/Terrain-following_radar

    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.

    Some of the systems are designed to avoid collisions with other aircraft and UAVs.They are referred to as "electronic conspicuity" by the UK CAA. [6]Airborne radar can detect the relative location of other aircraft, and has been in military use since World War II, when it was introduced to help night fighters (such as the de Havilland Mosquito and Messerschmitt Bf 110) locate bombers.

    NOE is used to minimize detection by hostile aircraft, airborne early warning and control surveillance and control systems, ground-based radar, or attack targets. [ 1 ] A high-flying aircraft can be detected by defense systems at long range, giving an air defense system time to react, alerting surface-to-air missile and anti-aircraft systems ...

    The Navy restarted the competition for a sense-and-avoid radar for the Triton in November 2014 with less ambitious requirements, including the ability to use data from ground radars as it approaches an airport, and a modular and scalable design that can be incrementally improved to meet evolving future operational and air traffic management ...

    en.wikipedia.org/wiki/Unattended_ground_sensor

    Flexnet™ is a Unattended Ground Sensor capability, [9] from the Swedish company Bertin Exensor, subsidiary of Bertin Technologies. It includes sensors with embedded processing, GPS, and radio communication. Those sensors are based on seismic-acoustic detection, passive infrared, electro-optical and magnetic detection techniques.

  9. Ground Master 200 - Wikipedia

    en.wikipedia.org/wiki/Ground_Master_200

    The Ground Master 200 (GM200) is a medium range AESA 3D radar manufactured by Thales Group. The GM200 can operate both as an independent air surveillance radar or as the sensor module of an air defence system. The GM200 also features a surface channel and a Rocket/Artillery/Mortar sense and warn capability. [1] [2]
