摘要
通过分析和总结以往激光警戒设备离轴探测距离的测试和评估方法,提出了一种基于概率统计和多次曲线拟合的评估新方法。利用试验外场的阵地保障条件,测得了典型指示激光源远场激光辐射照度分布,建立了单点处指示激光辐射照度概率分布模型,再通过多次曲线拟合得到离轴探测距离与指示激光辐射照度关系曲线,进而得出在任意探测概率下激光警戒系统的极限探测能力。
Through the analysis of the previous testing and estimating method, a new assessment method of off-axis detection distance for the laser warning system using probabilistic method and multi-times curve fitting was proposed. The distribu- tion of the farfield laser irradiance of the typical laser source was measured through outfield experimentation, and the distribu- tion model of the laser irradiance probability of the laser source on single spotting was established. Through the simulation calculation using the new method, the relation curve between the ofbaxis distance and laser irradiance was got and the limiting detection capability of the laser warning system under the condition of arbitrary detection probability was obtained.
