Abstract
This paper explores how pulse-diverse modulation of an FSK-PSK modulated pulse train enhances the flexibility to shape the size and distribution of the pulse train's ambiguity volume on the Doppler-delay plane. Pulse-diverse modulation compresses each pulse in the pulse train differently. Based on a priori information of the relative criticality of various Doppler-delay regions (e.g., the presence of strong clutter or jamming in a certain Doppler-delay sector would mean that the ambiguity function should ideally be small in that Doppler-delay sector) a cost function is formed to identify via a genetic algorithm the near-optimal FSK-PSK modulated pulse compression sequence for the entire pulse train.
