Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. [ 1 ]
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 ...
AN/FPS-124 unattended Radar (UAR), short range, doppler radar; AN/FPS-126, part of the SSPARS; AN/FPS-129, also called HAVE STARE; AN/FPS-132 Upgraded Early Warning Radar (UEWR) to upgrade SSPARS; AN/MPN-1 ground control radar; AN/MPN-2 ground control radar; AN/MPN-3 ground control radar; AN/MPN-5 ground control radar; AN/MPN-11 ground control ...
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
Ground radar (cf. airborne radar system) is a radar positioned on the ground and used for air defense (e.g., ground-controlled interception), command guidance (e.g., ground-directed bombing), air traffic control (i.e., radar control), instrument landing systems, radar bomb scoring, etc.. Ground radar may refer to: Air Route Surveillance Radar
The frequency of radio waves used by most radars, in the form of microwaves, propagate in straight lines.This generally limits the detection range of radar systems to objects on their horizon (generally referred to as "line of sight" since the aircraft must be at least theoretically visible to a person at the location and elevation of the radar transmitter) due to the curvature of the Earth.
Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.
The AMES Type 7, also known as the Final GCI, was a ground-based radar system introduced during World War II by the Royal Air Force (RAF). The Type 7 was the first truly modern radar used by the Allies, providing a 360 degree view of the airspace around the station out to a distance of about 90 miles (140 km).
