Abstract :
The authors mainly discuss some efficient imaging and speckle noise restriction algorithms in the Spaceborne SAR Azimuthy Imaging Processing (SSARAIP) based on the analyses of the spectral characteristics of spaceborne SAR echo signals (SSARES), range migration (RM) and speckle noise (SN). On the basis of the imaging models of targets on the ground, they also contrast the customed imaging mode (CIM) for fixed-targets and the moving-target´s imaging mode (MIM) in detail
