一种基于蒙特卡罗法的激光引信回波信号仿真技术

激光引信探测目标受试验条件的限制，获得真实数据代价很高。考核激光引信系统性能的有效方法是回波信号的数字仿真。一般的仿真方法缺乏对大气悬浮粒子后向散射的描述，难以模拟真实作战环境中气悬粒子对激光引信的影响，本文采用了一种基于蒙特卡罗法的激光引信回波信号仿真算法，模拟目标回波激光脉冲能量的同时，利用概率统计方法推导了气悬粒子后向散射的激光脉冲能号计算的理论公式，并给出了仿真激光引信回波信号的算法步骤和仿真结果。

A Monte-Carlo based Backscattering Signal Simulation for Laser Fuze

Its difficult to obtain the practical data of laser fuze reflected from target, for the lack of proper conditions for experiments. Numerical simulation is an effective method to evaluate the laser fuze system. Normal simulation methods can seldom do good at describing backscattering signal of the atmospheric aerosol, so they are hardly able to simulate the effect of aerosol on laser fuze. In this paper, a Monte-Carlo based technique was proposed, which can simulate not only the return signals form target, but also the backscattering signals from atmospheric aerosol. The theoretical formula using the probabilistic method was derived, and the algorithm and simulation results were given.
