不同压缩算法对雷达数据的压缩效果研究

摘要

Radar data compression plays an important role in the real-time data transmission ,compression algorithm di-rectly affects the efficiency of the transmission .By analyzing the actual navigation radar data ,on the basis of carrying out pretreatment ,run-length coding , Huffman coding and dictionary lookup LZW coding algorithm are understood and pro-grammed .The actual radar data collected is used as processing object ,three algorithms are used to compress ,the advantages and disadvantages of the three algorithms are analyzed comparatively ,the compression better compression algorithm is selet-ed for data compression ,real-time transmission is achieved .%雷达数据压缩在数据实时传输过程中起着重要的作用，压缩算法的好坏直接影响到传输的效率。论文通过对导航雷达实际数据的分析，在进行预处理的基础上，对游程编码、霍夫曼编码以及 LZW 字典查询编码算法进行理解与编程实现。利用实际雷达采集到的数据作为处理对象，分别用三种算法进行压缩处理，对比分析三种算法的优缺点，选择压缩效果较好的压缩算法进行数据压缩，达到实时传输的要求。
