提出了考虑探测概率曲线的激光告警设备作用距离的仿真方法。结合激光告警设备的探测概率曲线和大气湍流作用下的点光强起伏的概率分布,仿真得到激光单脉冲能量为10~(-5)J时,中等湍流强度(C_n~2=10~(-14)m~(-2/3))下激光告警设备的作用距离约为6.5km。实验结果证明这一方法是可行的。这一仿真解决了小孔径激光告警设备的作用距离外场评估费时费力的难题,为小孔径激光告警设备作用距离的评估提供了参考。
A simulation method of the working distance of the laser warning device considering probing probability curve is proposed. Combined with the probing probability curve of laser warning device and the probability distribution of point light intensity fluctuation under atmospheric turbulence, the simulation results show that the medium turbulence intensity (C_n ~ 2 = 10 ~ (- 14) m ~ (-2/3)) under the action of laser warning device about 6.5km. Experimental results show that this method is feasible. This simulation solves the problem of time-consuming and labor-intensive evaluation of the small aperture laser warning device in the field and provides a reference for the evaluation of the working distance of the small aperture laser warning device.
