| 摘 要： | 介绍了一种压缩雷达数据的方法,其主要编码方式是用FFT变换编码加上霍夫曼统计编码。对所采集的雷达数据按不同的量化比特进行了压缩实验,并对数据的压缩性能作了分析。分析表明,量化比特数越大,均方误差越小;而压缩比越小,压缩速度越快。用户应根据需要选取适当的量化比特数(如8位)。

| Abstract: | A method of radar data compression is introduced in this paper. The coding method is FFT conversion coding followed by Huffman coding. The radar data compression experiment is conducted with the different quantification bit number, and the compression performance is analyzed. The analysis indicates that the more quantification bit number,the less RMS error; the less compression ratio, the higher compression speed. Therefore, proper bit number should be determined by user. |
