The antenna area of distributed microsatellites radar system is usually smaller than the minimum SAR antenna area constraint, and there are range-Doppler ambiguities. So one key focus of this signal processing research is to develop processing approaches that exploit the added degrees of freedom of a spatially diverse formation to resolve inherent ambiguities of this sparse aperture distributed microsatellites radar system. This work proposed a Doppler ambiguity resolving method which makes the Doppler ambiguities null in Doppler domain using spatial filter of multiple phase centres.
