Abstract
Coherent pulse train processing gives improved Doppler resolution, compared to single pulse processing, but introduces range and Doppler ambiguities. Diversely coded pulse trains produce a weighted composite ambiguity function at the origin and cross-ambiguity terms at multiples of the pulse repetition interval. An idealised nonlinear suppression operator is introduced to suppress these terms, effectively reducing the total volume under the ambiguity surface. Nonlinear suppression is introduced to approximate ideal suppression operation and illustrated by example
