摘要
重点介绍了用双路对消抑制弹射式干扰的原理及结果。从理论上分析了双路对消的工作原理,并用模拟原始数据生成和成像处理技术对双路对消作了仿真实验。实验结果表明双路对消很好地抑制了弹射式干扰,同时也证实了双路对消技术的理论正确性。通过对干扰机定位误差和雷达飞行速度不满足对消条件时对抑制干扰的影响的分析,得出本技术对干扰机定位精度要求不高,对飞机飞行速度精度要求不高的结论。
A new jamming way to SAR (Synthetic Aperture Radar) named rebound is investigated and the method to suppress this kind of jamming is discussed. A new Algorithm named Two-Channel Cancellation for removing rebound jamming is investigated in detail, and the effect is got by simulation. A method of raw dada creation and reconstruction is used to simulate the jamming suppression effectiveness. After that, the precision of jammer orientation that needed by the algorithm is discussed. And finally, the precision demand of velocity of SAR is investigated too.
