SAR-GMTI 匀速运动虚假场景干扰信号快速生成方法
A fast jamming method for false uniformly-moving scene against SAR-GMTI
摘要
Abstract
The deceptive stationary scene jamming is not effective for countering synthetic apreture radar (SAR)and ground moving target indication (GMTI)radar systems.To solve this deficiency,a method which transforms the stationary scene jamming signals to uniformly-moving scene jamming signals in real time is proposed.First,the echo models of moving target and stationary target were analyzed.Then,a formula which describes the relationship between moving target echo signal and stationary target echo signal was derived.Based on this formula,a three-implementation-step of this method was presented as delay operation in range time domain,stretching transformation in azimuth time domain and phase compensation.Next,the computational complexity was analyzed.Finally,the simulation results indicate that the proposed method is effective to produce false uniformly-moving scene,through which the stationary scene and important ground moving targets can be protected against SAR-GMTI.关键词
