Answer: _Pulse Doppler RADAR_ type of RADAR routes the calculated Doppler shift through a series of frequency-filters (bandpass filters), which results in the ability to distinguish between targets of different velocities.
Explanation: A pulse-Doppler RADAR 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. It merges the characteristics of pulse radars & continuous-wave radars, which were formerly distinct due to the complexity of the electronics.
