雷达多普勒信号数据压缩研究

Study on Dated Compression of Radar Doppler Signal

在分析了多普勒信号的特性及与语音信号的区别后 ,采用自适应离散余弦变换算法对多普勒信号进行了压缩编码 ,在中等编码速率下得到了较好的压缩编码效果。文中提出了相关 -自适应离散余弦变换 (C- ADCT)压缩编码算法 。

In this paper,after the characteristic of doppler signal and the difference with voice signal are analyzed,the algorithm of ADCT is used to compress the doppler signal. At a medium encoding rate,this algorithm can give a good compression encoding performance. The correlation ADCT algorithm is presented in this paper,which improves the anti noise performance of ADCT.
