基于星载视频SAR的海上运动目标监视方法
Maritime Moving Target Monitoring Method Based on Spaceborne Video SAR System
摘要
Abstract
Traditional SAR processing method have been unable to meet the increasingly complex battlefield environment, especially on detecting and tracking moving target.For this situation,in this paper,a new method to monitor moving target at sea,spaceborne video SAR,which could realize continuous observation over the interesting area to obtain all-around tar-get information was introduced.Firstly,the video SAR theory was analyzed and it was necessary to use echo data overlap pattern to ensure fluency of video.Secondly,through image registration and parameter inversion,moving target's azimuth and range information could be obtained.Then traditional back projection(BP)imaging algorithm was improved to meet vid-eo SAR's high effectiveness.This BP algorithm could not only save resources,but also improve computing efficiency.Final-ly the simulation results justified the superiority of the new method and the extracting accuracy in movement information.关键词
