摘要
为了解决雷达视频信号存储、传输问题,需对其进行压缩处理。根据雷达原始视频信号的特点,分析了常用的雷达视频信号压缩方法与分类,并阐述了各压缩方法的优缺点;提出了一种基于JPEG 2000国际标准的用于雷达视频信号的压缩方法,并对压缩系统进行分析设计。最后对一幅2 048×2 048图像进行压缩,分析结果,压缩率达70%。
In order to solve the problems of radar video signal transmission and memory,it is necessary to compress it first.The conventional methods of the radar video signal compression are analyzed base on the characteristic of the original radar video signal,and the disadvantages of each method are elaborated.A method applied to radar video signal compression is proposed,and then the compression system is designed base on JPEG 2000 international standard.The compression results of a 2048×2048 picture is offered and analyzed.
