针对合成孔径雷达(SAR)平台相对干扰机运动的非合作性导致欺骗干扰效果较差的问题,提出了一种基于序贯引导的SAR场景欺骗干扰新算法。首先,构建SAR平台的序贯最小二乘定位模型;然后建立了干扰信号的引导调制模型,并推导了其相对无调制引导时的干扰性能优势。仿真表明,该算法提高了欺骗场景的逼真性。

A new deception-jamming algorithm against SAR based on sequentially booted information of the platform location is studied in this paper.Firstly,the mathematical model of the platform location is established on the base of sequential estimation method.Secondly,the pulses carrying certain kind of information are booted adaptively to the platform.Lastly,the deception model considering the booting effects is educed basing on the range-doppler algorithm.Simulation shows the effectiveness of this algorithm.
