Research on sar data compression
合成孔径雷达数据压缩的研究

The correlation characteristics of SAR raw data, interim data and image data are studied. A region adaptive compression method based on JPEG algorithm is developed and applied to the compression of SAR image data. Furthermore, on the basis of this method, a compression method of the SAR complex image data is developed, which reserved the phase information and had low bit rate comparing to direct quantization.
