Abstract: SAR raw data compression by using lifting wavelet transform and block adaptive quantization is studied based on the known results, that a block normalized SAR raw signal is a Gaussian stationary process and the feature of wavelet transform can eliminate the signal correlation for its multiresolution decomposition. Through the experiment, the results achieved are satisfied.

Key words: SAR raw data compression, block adaptive quantization, wavelet transform
