  • The phase information becomes more and more important in the field of SAR applications. Considering the statistical independent property between phase and amplitude of SAR raw data, a new method is provided that the amplitude and phase of raw data are compressed respectively. In this paper, a flow chart shows that procession of the algorithm. The algorithm performance is analyzed based on real SAR raw data. Finally, the AP (Amplitude Phase) algorithm is compared with the BAQ algorithm. The performance of the AP algorithm is proved to be fine, especially in terms of the reservation of phase information.
