Abstract :
Attitude stability is a very important parameter for the platform design of scanning synthetic aperture radar (ScanSAR) satellite. In this paper, the effect of satellite attitude error on the Doppler parameters is derived in detail. And the effects of Doppler centroid frequency error on spaceborne ScanSAR mosaic in azimuth are analyzed, to provide a theoretical guideline for the design of spaceborne ScanSAR system, as verified by simulations.
