采用建模仿真的方法研究了红外干扰机对四元正交探测器的干扰效能。分析了四元正交探测器导引头的目标识别机理和干扰信号对目标识别的影响,建立了导弹总体仿真模型和干扰机干扰下的调制盘导引头和四元正交探测器导引头的目标识别模型。通过仿真定量地比较了不同压制比和占空比下红外干扰机对两种典型红外制导导弹的干扰效果。仿真结果显示,红外干扰机对四元正交探测器导引头的干扰效果明显不如对调制盘导引头的干扰效果;增大压制比可提高干扰机的干扰效能;当占空比为0.5时,干扰机对四元正交探测器导引头的干扰效能最大。
The interference performance of infrared jammer on quadrature quadrature detector was studied by using the method of modeling and simulation. The target identification mechanism of the quadrature detector seeker and the influence of the interference signal on the target identification are analyzed. The guidance of the modulation disk seeker and quaternary quadrature detector under the overall simulation model of the missile and jammer jamming is established Head of the target recognition model. Through simulation, the interference effects of infrared jammers on two typical infrared guided missiles were compared quantitatively under different compression ratio and duty cycle. The simulation results show that the jamming effect of the infrared jammer on the quaternion quadrature detector seeker is obviously not as good as the jamming effect on the turntable seeker. Increasing the suppression ratio can improve the interference performance of the jammer. When the duty cycle is 0.5 , The jammer has the highest interference efficiency on the quadrature detector seeker.
