    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.

  4. Pulse-Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Pulse-Doppler_radar

    Pulse-Doppler radar for aircraft detection has two modes. Scan; Track; Scan mode involves frequency filtering, amplitude thresholding, and ambiguity resolution. Once a reflection has been detected and resolved, the pulse-Doppler radar automatically transitions to tracking mode for the volume of space surrounding the track.

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

    Pulse Doppler radar may have 50 or more pulses between the radar and the reflector. Pulse Doppler relies on medium pulse repetition frequency (PRF) from about 3 kHz to 30 kHz. Each transmit pulse is separated by 5 km to 50 km distance. Range and speed of the target are folded by a modulo operation produced by the sampling process.

    Blighter B202 Mk 2 also includes high-quality Doppler audio and is a "Multi-Mode and Multi-Role" radar. The modes including radar modes for quick scan ('Vortex Fast-Scan') with audio for fast search and long dwell modes small scan for high probability of detection of crawlers also can be used with Doppler audio for target recognition.
