摘要
首先分析了电扫偶极子相控阵雷达空域极化特性,讨论了主极化及交叉极化分量在测角时振幅和差比值的不同。在简述交叉极化角欺骗干扰原理之后,结合单脉冲极化雷达的角度测量算法,分析了对相控阵雷达进行交叉极化角度欺骗干扰的影响参数及干扰效果。仿真结果表明,对相控阵单极化雷达而言,该方法是一种颇具潜力的新型干扰方法。
First the spatial polarization characteristics of the phased array radar is analyzed,and the difference of the amplitude sum-difference ratio,when the main polarization and the cross polarization components to measurement angle,is also discussed.After the principle of cross polarization angle deception jamming is introduced,the influence parameters and jamming effect of cross polarization angle deception jamming are analyzed.Simulation results show that the proposed method is a promising new method for phased array radar.
