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.
Joseph William DeNardo (November 27, 1930 – June 15, 2018) was an American meteorologist best known for his work at WTAE-TV in Pittsburgh. [1] He was known for his 1994 advertising campaign, "Joe Said It Would." [2] DeNardo lived in Moon Township, Pennsylvania, with his wife of nearly 60 years. When he retired in 2005, after 45 years on the ...

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.
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.
