摘要
合成孔径雷达转发欺骗干扰技术主要通过移频和距离向延时调制实现,常规转发的干扰信号具有规律性强、复杂度低等缺点。针对这种情况,提出了混沌移频和混沌延时相结合的干扰技术。干扰信号具有复杂程度高、分布平稳、干扰范围广等优点,且和发射信号相干。干扰能够产生区域压制干扰的效果,相对于噪声干扰,只需要较小的干扰功率。
Transmitting Deception Jamming to SAR is mainly implemented through Shift-Frequency and range direction delay. Jamming signal is too ordinary and not complex enough in general jamming method. Based on these, Shift-frequency jamming and chaotic delay is proposed in this thesis. Jamming signal is complex enough and its jamming range is extended. In this way, the effect is like as barrage jamming, but less power is needed opposite to noise jamming.
