【摘要】：论文针对多通道SAR-GMTI提出一种新的干扰方法:基于旋转天线的SAR-GMTI 2维余弦调相转发干扰。对干扰机截获的SAR信号进行距离向余弦调相的同时,利用干扰机天线旋转来实现方位向余弦调相,解决了工程上无法实现方位向余弦调相的难题,并采用三通道干涉对消方法分析了其对GMTI的对抗性能,该方法对SAR和SAR-GMTI均可产生2维"网状"多假目标干扰效果,可同时保护地面运动目标和静止目标。理论分析和仿真实验验证了该干扰方法的可行性和有效性。
[Abstract]:In this paper, we propose a new jamming method for multi-channel SAR-GMTI: SAR-GMTI 2-dimensional cosine phase modulation jamming based on rotating antenna. The range cosine phase modulation of the SAR signal captured by the jammer is carried out, and the azimuth cosine phase modulation is realized by rotating the antenna of the jammer, which solves the problem that the azimuth cosine phase modulation can not be realized in engineering. The three-channel interference cancellation method is used to analyze the performance of GMTI. This method can produce 2-D "mesh" multi-false target jamming effect on both SAR and SAR-GMTI, and can protect both ground moving target and stationary target simultaneously. Theoretical analysis and simulation results show that the method is feasible and effective.
