Method for laser weapon target intensity parameter assessment

通过对不同应用情况下激光武器靶面强度参数定义及其影响因素的分析,建立了激光武器靶面强度参数评估模型。针对评估模型中的大气传输模型、靶面光斑形状分析、靶面长曝光功率密度、靶面瞬时功率密度概率分布等问题进行了详细的讨论,并给出了相应的计算方法和实验数据分析方法。初步提出了使用蒙特卡洛方法来解决评估模型中评估参数的随机性问题,并对评估参数统计分布的获取进行了简要说明。

Based on the analysis for definition of laser target intensity parameter in various applications and its influence factor, an assessment model of laser target intensity parameter is developed. Detailed discussions for laser propagation,laser profile on the target, long exposal intensity on target, and instantaneous intensity probability distribution are given. The corresponding computation methods and experimental data analysis methods are also discussed. In order to deal with the randomicity of assessment parameter, the Monte Carlo method is introduced, and the acquiring method of parameter probability distribution is given.
