首先对矢量量化编码的基本原理进行了讨论,并对矢量量化编码中的码书生成方法进行了研究,在此基础上提出了SAR原始数据矢量量化编码中一种码书生成的改进方法。文中还介绍了利用改进的码书对SAR原始数据进行量化编码的应用,得到了较好的效果,并给出了实验结果。

In this paper, we discuss the principle of vector quantization and research the code book generating method of vector quantization. Based on the code book generating method, we put forward an improved code book generating method for SAR raw data vector quantization coding. We introduce the SAR raw data compression coding application with the improved code book and get well experiment effect.
