Abstract

This paper concentrates on the implementation of spaceborne SCANSAR mode which is developed in the stripmap spaceborne SAR system with variable look angle.SCANSAR signal parameters are determined and imaging algorithm for SCANSAR data with the large range migration is presented.Several SCANSAR performance parameters are analyzed and particular attention is given to ambiguity and noise equivalent

.With the requirement of spatial resolution

SCANSAR mode is designed in a large range migration spaceborne SAR system

the SCANSAR echo data is simulated and image is obtained.
