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 ...
Radar sites had the ability to control interceptions by themselves, while the overall recognised air picture was compiled and directed at Strike Command headquarters. To complicate the use of radar jammers, several new radars were introduced that operated across a wide band of frequencies from L to S (C to F in NATO terms). Peacetime radars ...
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 ...
By 1972 NADGE was converted into NATINADS consisting of 84 radar sites and associated Control Reporting Centers (CRC) and in the 1980s the Airborne Early Warning / Ground Environment Integration Segment (AEGIS) upgraded the NATINADS with the possibility to integrate the AWACS radar picture and all of its information into its visual displays.
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.
A ground-based system periodically sent out pulses which the airborne transponder returned. By measuring the total round-trip time on a radar's oscilloscope, the aircraft's range could be accurately determined even at very long ranges.
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..
