This paper proposes a new approach for efficient SAR raw data compression which consists of first compressing the raw data with the block adaptive quantizer (BAQ) approach and then performing a compression with the vector quantizer (VQ). Further improvements are possible selecting different compression ratios with fuzzy control systems whereby the mean data rate is nearly maintained.
