Review of Radar Data Lossy Compression
Mao Wenshen · Electronic Engineer · 2008
The radar signal has very large volume of data.If not compressed for storage or transmission, the resource is used tremendous.This paper summarizes the characteristics of the radar data,categories the common radar data compression methods,and gives the evaluation indicators.The flow and key technology of several compression algorithms which are RLE,single trigger unit,DCT and wavelet analysis for lossy com- pression are introduced.Combined with evaluation indicators,the various algorithms are compared,and a rec- ommended compression method is proposed.The compression flow is further divided into de-noising and com- pression,and the importance of de-noising in radar data compression is emphasized.Some useful conclusions are drawn.
