摘要

本文探讨了FSK-PSK调制脉冲序列的脉冲分异调制如何增强脉冲序列在多普勒延迟平面上模糊量大小和分布的灵活性。脉冲分异调制以不同的方式压缩脉冲序列中的每个脉冲。基于各种多普勒延迟区域相对临界性的先验信息(例如，在某个多普勒延迟扇区中存在强杂波或干扰将意味着该多普勒延迟扇区中的模糊函数理想情况下应该很小)，形成一个代价函数，通过遗传算法识别整个脉冲序列的近最优FSK-PSK调制脉冲压缩序列。

Pulse-diverse radar/sonar FSK-PSK waveform design to emphasize/de-emphasize designated Doppler-delay sectors

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.
