蒙特卡洛方法在坦克火控系统误差分析中的应用

Application of Monte Carlo Method in Error Analysis of Tank Fire Control System

影响坦克火控系统总体精度的误差源众多,且各误差源误差值随着时间的推移呈现随机分布.为了找出各误差源的误差值与系统总误差的关系,及所谓的误差传递关系,应用蒙特卡洛法建立了火控系统的误差分析数学模型.应用该模型模拟仿真实际射击,得到了火控系统输入量误差与输出量误差之间的传递关系,结果表明输入量误差对高低分量的影响大于水平分量,从而找到影响射击精度的主要误差源.

There are many sources of input error affecting the tanker＇ s fire control system＇ s total precision,and the input errors present random distribution over time. In order to find out the relationship between input errors and the total system error,which is called error transfer relation, the total fire control system error analysis mathematical model is established by using the Carlo method. It can simulate actual shooting to obtain the error transfer relation between inputs and outputs. The result shows that the vertical input error affects more than the horizontal input error and can be rergarded as the primary error source which influences the shooting precision.
