2. Doppler radar - Wikipedia

   en.wikipedia.org/wiki/Doppler_radar

   A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.

3. NEXRAD - Wikipedia

   en.wikipedia.org/wiki/NEXRAD

   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 ...

4. Frequency ambiguity resolution - Wikipedia

   en.wikipedia.org/wiki/Frequency_ambiguity_resolution

   Radar pulsing causes a phenomenon called aliasing, which occurs when the Doppler frequency created by reflector motion exceeds the pulse repetition frequency (PRF). [1] This concept is related to range ambiguity resolution. Doppler frequency shift is introduced onto reflected signals used by radar.

   Doppler Radar image on Dec. 21, 2024 "At first glance, it seems like a pretty boring radar picture across the Northeast (Saturday) morning," said FOX Weather Senior Meteorologist Greg Diamond.

7. Pulse-Doppler signal processing - Wikipedia

   en.wikipedia.org/wiki/Pulse-Doppler_signal...

   Pulse-Doppler signal processing is a radar and CEUS performance enhancement strategy that allows small high-speed objects to be detected in close proximity to large slow moving objects. Detection improvements on the order of 1,000,000:1 are common.

   However, since humans reflect far less radar energy than metal does, these systems require sophisticated technology to isolate human targets and moreover to process any sort of detailed image. Through-the-wall radars can be made with Ultra Wideband impulse radar, micro-Doppler radar, and synthetic aperture radar (SAR). [5] Imaging radar; 3D radar
