摘　　要：针对工程应用中雷达视频数据量大、难于实时传输的问题,分析了雷达视频数据的信息冗余和信号相关等特点,用3种雷达视频数据压缩算法对实际采集的某型雷达视频数据进行压缩、解压缩仿真并作了比较。结果表明:小波变换、游程编码和霍夫曼编码具有较高的压缩比和较好的信号恢复质量,具有一定的实用价值。According to the fact that radar video data is large and hard to real-time transmission in the engineering application, this paper analyzes the characteristic of information redundancy and signal correlation of radar video data, and proposes three compression algorithms of radar video data, compression and decompression are done with real radar data using these algorithms, the results prove the algorithm that use wavelet transform ,RLE and Huffman has a higher compression rate and a better quality of signal recovery and has some practicability.
