Abstract :
ScanSAR mode is an important direction in spaceborne SAR development, which causes new problems for radiometric correction. The critical techniques for ScanSAR radiometric correction are studied in this paper. Through analyzing those special radiometric variations in ScanSAR images, this paper has explored the approaches for scalloping compensation and beam band correction. By means of simulation, the feasibility of the radiometric correction technologies is verified.
