N2 - 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 based on wavelet packet transform (WPT) after a thorough analysis on the decomposed wavelet packet coefficients of the amplitude. By using the real SAR raw data, the performances achieved in terms of certain parameters have been evaluated. The results show that this algorithm is superior to the traditional BAQ algorithm, simultaneously in terms of the reservation of phase information.
