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 ...
SAR is a type of radar that is sensitive to linear and geometric features on the ground. [4] It is also important to include a method called ground truthing , or the process of physically visiting (on foot) the localities surveyed to verify the data and help inform the interpretation.
The first distance-based navigation system was the German Y-Gerät blind-bombing system. This used a Lorenz beam for horizontal positioning, and a transponder for ranging. A ground-based system periodically sent out pulses which the airborne transponder returned.
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.
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.
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..
