一种基于LZW算法的PDW数据压缩方法

PDW数据是ESM设备获得的重要情报之一,是分析目标辐射源信号特征的关键数据。在某些分布式ESM系统中,为了实时获取PDW数据,需要将PDW数据通过无线数据链下传。分析了PDW数据压缩在分布式ESM系统中应用的必要性,介绍了LZW压缩算法的基本原理和实现方法,最后详细介绍了关联比较器与LZW算法相接结合的PDW数据压缩的实现方法。

A banausic LZW method for compressing PDW data

The PDW data is a kind of important information that the ESM equipment acquired, and it is the key data in analyzing the characteristic of the target radiation source. In the distributed ESM system, in order to obtain the real-time PDW data, the PDW data needs to be transmitted through wireless data chain. The necessity of PDW data compressing in ESM systems is analyzed,and the basic principle and realization methods of LZW are introduced. At last, the compressing method of PDW data through combining the related compare and LZW is introduced.
