| 摘 要： | 合成孔径雷达ＳＡＲ数据率高、数据量大，对ＳＡＲ原始数据的压缩可以降低对数传和数据存储的要求。文中用ＳＢＡＳＡＰ－ＳＡＲ原始数据对合成孔径雷达信号统计模型进行了研究，提出了一种２ｂｉｔ自适应量化编码方法，并用ＳＥＡＳＡＴ—ＳＡＲ原始数据进行了编－译码实验，获得了该２ｂｉｔ量化编码器的性能指标测试结果。

| Abstract: | Synthetic aperture radar (SAR) Produces high bit flow and large amoint of raw data. Thecompression of raw data will both the data communication and storage. In this paper the SEASAT-SARraw data's statistical property is analyzed and the SAR staticstical model is set up. Based on this model, anoptimal SAR raw data quatization coder is realized.The choice of the coder's parameters is also discussed.Atlast,the coder's performance parameters are measured with the SEASAT-SAR raw data. |
