激光损伤四象限探测器对制导武器的影响

对激光损伤四象限探测器对制导武器的影响进行了研究。首先，简述了激光硬损伤光电探测器机理和四象限探测器目标探测定位原理；接着，建立四象限探测器模型，针对不同损伤情况，计算了归一化探测曲线和探测器偏移量；然后，将不同损伤情况下的角偏差信号送入激光制导炸弹运动控制模型，得到了不同四象限探测器损伤状态下激光制导炸弹弹道曲线；最后，分析了四象限探测器不同损伤距离下激光制导武器的脱靶量。研究表明，四象限探测器损伤程度和损伤距离都会对激光制导武器产生影响。该研究结果对大功率激光压制半主动激光制导武器效果评估有一定帮助。

Influence of laser damage quadrant detector on laser guided weapon

Analysis of laser damage quadrant detector(QD) for laser guided weapon was presented in this paper. Firstly, the principle of laser damage photoelectrical detectors and QD detection theory were shown, detection bias and normalized detection curve were calculated based on the quadrant detector model. Then, Laser guided bomb trajectory simulated by weapon control model in different laser damage level were studied. Finally, undershoot value of laser guided bomb was discussed in different QD's laser damage distance. The research indicates that QD's laser damage level and damage distance influencing the laser guided weapon, and the result will be helpful for the effect evaluation of blanket jamming to laser guided weapon.
