A method of operating a pulse-Doppler radar system includes the steps of generating a plurality waveforms, with each waveform comprising a plurality of pulses generated with a staggered pulse repetition frequency (PRF) from pulse to pulse. Received reflected return signals from the generated plurality of waveforms are filtered by a plurality of Doppler filters that span an entire required Doppler visibility range.
