NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
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 nondestructive method uses electromagnetic radiation in the microwave band ...
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
Doppler on Wheels (or DOW) is a fleet of X-band and C-band mobile and quickly-deployable truck-borne radars which are the core instrumentation of the Flexible Array of Radars and Mesonets [1] affiliated with the University of Illinois [2] and led by Joshua Wurman, with the funding partially provided by the National Science Foundation (NSF), as ...

Number built. 9 – Lockheed Martin 420K. 2 – Lockheed Martin 275K. Map all coordinates using OpenStreetMap. The Tethered Aerostat Radar System ( TARS) [ 2] is an American low-level airborne ground surveillance system that uses aerostats ( moored balloons) as radar platforms. Similar systems include the EL/M-2083 and JLENS.
