摘要
文中通过分析机载雷达空时信号模型,提出了针对空时自适应处理器的散射波多维欺骗干扰方法,根据多普勒频率对方位余弦的依从性,利用角反射器与机载雷达的几何关系构成角度欺骗,并通过干扰机调制及与雷达平台的相对运动产生虚假的多普勒信息,解决了传统空时自适应处理干扰信号维度单一的问题。分析了干扰机不同飞行路径时假目标多普勒频率对角反射方位余弦依从性的数学模型,最后通过仿真验证了干扰效果。
The scattered wave multi-dimension deception jamming method for space-time adaptive processing（STAP） is proposed in this paper by analyzing the airborne radar space-time signal model. According to the compliance performance of Doppler frequency to orientation cosine, the problem of traditional uni-dimension STAP jamming signal is solved by generating angle deception jam- ming through taking advantage of the geometrical relationship of corner reflector and airborne radar, and faking Doppler frequency through jammer modulation and radar relative motion. The different compliance performance model of Doppler frequency to orienta- tion cosine of different jammer flight path is analyzed. The simulation resuhs show that this jamming method is valid.
