Abstract
In this paper, a fast BAVQ algorithm in SAR raw data compression is proposed. First, to reduce the data dynamic range, block adaptive quantization of raw data is implemented and the sign bit of raw data is coded separately. And then, VQ is applied in the absolute value of the raw data. The result of experiments shows that the complexity of VQ has been greatly reduced and the process of searching codebook can be simplified
