摘要
在巡航导弹飞控数据链传输系统中,高效的图像压缩编码方法能降低图像数据传输和弹载终端对图像数据存储的负载。采用了一种压缩效率高,易于硬件实现的基于小波变换的图像压缩编码方案,并进行编解码算法分析和性能仿真。仿真表明,在满足飞控数据链压缩比大于15:1时所恢复的图像,人眼主观判图效果好,PSNR达到约35dB。
In cruise missile flight control data-link transmission system, effective image compression can be reduce load of transmission and storage information in missile-berne terminal. A low complexity and high implementation image compress method based on wavelet transform is presented in this paper, its algorithm is designed, and its performance analyzed. The results show image recovery can be satisfied with human active vision, and PSNR is about 35dB when image compression ratio is 15：1.
