Preliminary Report on Pulse Compression Waveforms and Their Application to Waveform Agility

摘要

Pulse Doppler radars predominantly transmit the same pulse compression waveform pulse to pulse. This produces good Doppler performance in a jammer free environment. But in a jammer environment the transmitted pulses can be captured by a digital RF memory (DRFM) and retransmitted creating false targets. By introducing pulse to pulse waveform agility the effectiveness of the jammer can be greatly reduced.
