Airborne Multi-Frequency-Band SAR System And Its Information Processing

摘要：

This paper describes the design of a Multi- frequency Band (MFB)SAR system and the flight tests,and discusses the methods of image formation,registration and fusion. Some experiment results are also presented. The MFB SAR system works in time-division mode so as to improve the compatibility of subsystems and to reduce the volume and the weight of the system.The MFB SAR images of the same scene are presented and some conclusion is made from the flight tests.Nonlinear Chirp Scaling algorithm is used to form the MFB SAR images.The problems of motion compensation for P-band SAR are analyzed.A new registration method,which can rectify the coordinates of the MFB SAR images with less than 1 pixel of registration error,is introduced.Finally,the MFB SAR images are fused based on the GHM multi-wavelet transform.
