摘要
由于雷达视频信号数据量非常巨大,在对雷达情报的传输和记录时都要求进行相应的数据压缩。依据雷达视频信号的特点和人眼的视觉特性,提出并详细分析了一种基于小波变换域的雷达视频信号压缩算法,并结合某型雷达信号记录仪采集的数据进行测试,验证结果表明,算法取得了较好的压缩效果,完全满足该雷达信号记录仪的需要。
Radar intelligence must be compressed before transmission and recording because the quantities of radar video signal are very large.According to the characteristic of radar digital video and vision feature,this paper proposes a novel compression coding algorithm of radar video signal based on wavelet transforming.The experiment is combined with the development of Radar Intelligence Recording Apparatus,and the results show that methods are efficient and meet actual demands completely.
