高功率YAG激光对激光导引头压制干扰的效果评估与理论分析

推导出计算高功率YAG激光直接或间接照射在激光导引头前或其四象限探测器上的能量密度公式和峰值功率密度公式,提出致盲或深度饱和评估准则.通过激光干扰时间序列图分析,指出由于激光导引头光电传感器饱和驰豫时间太小,非同步压制干扰无效是体制问题;并提出,可以借用激光角度欺骗干扰中的编码识别技术,控制高功率YAG激光脉冲的发射时机,让压制干扰刚好屏蔽激光导引头的信号探测时间波门,从而使得压制干扰有效.

The effect assessment and theory analysis of high power YAG laser induced suppressed disturbing in laser-guided weapon

The formulas for calculating the energy density or peak power density of laser before the laser-guided head or on its four quadrants detector irradi- ated by high power YAG laser are deduced.The assessment rules that the laser blinds or deep saturates the optoelectronic detector are proposed.It is found out that it is the problem of the interference principle that causes the failure of the high power laser unsynchronized suppressed interfering the laser-guided system. It is suggested that the problem could be solved by using the decoding technology which is used in the laser direction deceive system that counterworks laser-guid- ed weapon.Then the output time of the high power laser pulse could be controlled accurately to saturate the hser-guided bead's four quadrants detector during its signal detecting time window,which could disable the laser-guided weapon efficiently.
