Abstract：Such factors as complicated spaceborne SAR orbital motion, earth rotation, earth surface curvature etc. make the realization of spaceborne SAR/GMTI different from airborne SAR/GMTI. In this paper, the property of three-antenna spaceborne SAR is analyzed firstly, and then the method of airborne SAR/GMTI processing is given and analyzed. On the basis of airborne SAR/GMTI, an algorithm of spaceborne SAR moving target detection, radial velocity estimation and relocation based on DPCA technique is presented. Finally, spaceborne SAR/GMTI computer simulation results validate its effectiveness.
