对激光半主动制导武器的角度欺骗干扰的效能评估

Assessment of effectiveness on angle deceptive jamming to semi-active laser-guided weapon

角度欺骗干扰是一种有效的对抗激光半主动制导武器的措施,对角度欺骗干扰的效能进行评估在军事上有重要意义。传统的评估方法是采用仿真软件对激光导引头的弹道进行仿真,几乎不考虑目标指示器的影响。以激光半主动制导炸弹和目标指示器组成的系统为对象,依据射击效率理论,计算了无干扰时激光半主动制导炸弹对目标的杀伤概率,并指出激光角度欺骗干扰相当于在激光半主动制导武器系统中引入系统误差,从而造成其对目标杀伤概率的下降。角度欺骗干扰成功的关键在于告警系统对制导信号的探测、识别能力以及干扰激光器的超前同步发射能力和对目标指示器的摧毁能力。通过计算干扰前后激光半主动制导炸弹对目标杀伤概率的变化得出了对其进行角度欺骗干扰的效能。

It is one of the efficient measures for angle deceptive jamming to semi-active laser-guided weapons. It is very important to assess the effectiveness of angle deceptive jamming in military either. Simulation software is conventionally used to simulate the trajectory of laser-guided seeker for the evaluation of angle deceptive without considering the effect of target indicator. In this paper, the system which was consisted of laser-guided bomb and target indicator was taken as the study object. Kill probability of semi-active laser-guided bomb without jamming was calculated based on the theory of firing efficiency. The system error, which was introduced by angle deceptive jamming that made the kill probability of target reduce was printed out. Detection and recognition probability of laser warning system, look-ahead synchronous transmitting of jamming laser beam and the kill probability for target indicator were determinative factors to laser angle deceptive jamming. The effectiveness on angle deceptive jamming to semi-active laser-guided weapon was obtained based on decline of kill probability after jamming.
