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。
In this paper, by analyzing the space-time signal model of airborne radar, a multidimensional deception jamming method based on Doppler frequency for azimuth cosine is proposed, which is based on space-time adaptive processor. Using the geometry of corner reflector and airborne radar The relationship constitutes the angle of deception, and through the interference machine modulation and relative motion with the radar platform to generate false Doppler information, to solve the traditional space-time adaptive processing interference signal single problem. The mathematical model of the cosine compliance of the false target Doppler frequency in different flight paths is analyzed. Finally, the interference effect is verified by simulation.
