Difference between pulse radar and pulse Doppler radar

A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object’s velocity .

The pulse length is usually called the PULSE WIDTH in radar systems. The pulse interval, or the time from the beginning of one pulse to the beginning of the next, is determined by the number of pulses which are transmitted in a given period of time . In radar, we measure all time in seconds (or fractions of seconds).

The Doppler effect shifts the received frequency up or down based on the radial velocity of target (closing or opening) in the beam, allowing for the direct and highly accurate measurement of target velocity. A Doppler radar is a radar that produces a velocity measurement as one of its outputs .
