Abstract: Because of the widely dynamic range of ground targets' backscattering coefficients, original GB-SAR image has disadvantage of low contrast ration [1]. In order to enhance contrast, classical method and improved methods based on statistical property of GB-SAR images are studied. Finally, the feasibility and effectiveness of the improved methods are validated with experimental datasets.
