摘要
该文介绍了合成孔径雷达原始数据压缩的意义和重要性，接着给出了BAQ算法的实现程序．最后，进行了4bitBAQ的压缩仿真和解码成像，对原始数据、4bitBAQ压缩结果进行了成像比较。
The role and signification of SAR raw data compression are introduced. Program of BAQ is given.Finally, the 4bit BAQ compression simulation and the decoded image ia also provided. The difference between the image from raw data and the 4 bit BAQ compression result is compared.
