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 ...
Radar systems operating at extremely high frequency offer enhanced Doppler resolution for a given coherent processing interval. [18] This increased resolution allows access to micro-Doppler signatures (MDSs), where micro-Doppler refers to Doppler modulations caused by the oscillatory movement of a target's structural components, in contrast to ...
Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to provide multiple imaging modes for recording images with different swath width, resolution and polarizations, see the figure for more details. In stripmap mode (spatial resolution of 3m), it needs 10 weeks to map global Earth's landmass.
A high-resolution, north-oriented, coloured radar picture is displayed on PC display. The radar display can either be in a Plan position indicators (PPI) display, or a B-Scope display. The display also has provision for digital geographic map overlay, which allows the target data to be integrated with tactical data for use by ground forces and ...
The AN/APG-66 radar is an X-band [1] solid state medium range (up to 80 nautical miles (150 km; 92 mi)) pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation (now Northrop Grumman) for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83.
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
