Adaptive pulse-diverse radar/sonar waveform design

Abstract

This paper devises an adaptive pulse-diverse compression waveform design method: echoes from earlier pulses of the pulse train brought back target/jamming/Doppler information of the actual battlefield environment. The present scheme allows the use of this information to assign the relative criticality of various Doppler-delay regions with respect to the waveform ambiguity function. For example, the presence of strong clutter or jamming in a certain Doppler-delay region means that the waveform ambiguity function needs to have very low magnitude in that Doppler-delay region. Based on this adaptive criticality criterion, the compression waveform is designed in real time for the latter pulses in the same pulse train to fit the actual battlefield environment confronting the radar/sonar system.
