FDA对比幅法单脉冲测向的角度欺骗

基于相控阵的干扰机在对目标雷达施放干扰的过程中，其辐射信号会被敌方的无源探测雷达所捕获。基于频率分集阵列(FDA)干扰机结构，提出一种针对敌方相邻天线比幅单脉冲测向系统的角度欺骗方法。首先，在建立FDA模型的基础上计算出FDA雷达的半功率波束宽度。然后，将半功率波束宽度代入相邻天线比幅单脉冲测向系统，通过仿真，系统分析了FDA干扰机对比幅法无源测向系统的角度欺骗效果及误差影响。仿真结果表明，远场条件下，FDA干扰机对测向系统具有良好的角度欺骗效果。 

Angle deception effect of FDA on amplitude comparison direction finding system with single pulse

In the process of jamming the target radar, the radiated signal of the phased array-based jammer will also be captured by the enemy's passive detection radar. Based on FDA jammer, this paper proposes an angle deception method for the adjacent amplitude comparison direction finding system. First, the half-power beamwidth of the FDA radar is calculated based on the FDA array model. Then, the half-power beamwidth is substituted into the adjacent amplitude comparison direction finding system. Finally, through simulation, the angle deception effect and error influence of the FDA jammer on the direction finding system are analyzed. The simulation results show that, under far field conditions, the FDA jammer has a good angle deception effect on the direction finding system.
