摘　　要：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。The simulation method of the detection distance of the laser warning equipment on account of its detection probability curve was presented. The detection distance of the laser warning equipment was simulated with its detection probability curve and the probability-density distribution of laser scintillation of a certain spot induced by atmospheric tubulence. The effective range was 6.5km with the laser power of 10-5J and Cn2 of 10-14m-2/3. The method was proved feasible by the experiment. The simulation was simple and effective compared to the power and time-consuming experiment,which presented good reference for the evaluation of the detection distance of laser warning equipment.
