Title Research on the Monte Carlo Statistical Algorithm of Archibald’s Hit and Damage Probability
Abstract
This paper mainly describes the research on Archibald’s hit probability and damage probability in Monte Carlo statistical method. The development background of Monte Carlo method and Archibald firing are introduced. Then Archibald firing error analysis and firing test accuracy estimation are proposed. The Archibald’s ballistic equation and firing table are also studied. Based on the 3 DOF ballistic equations, First, the MATLAB codes to solve the equations are designed, and the coresponding anti-aircraft artillery hit flight figures are plotted.Second, the Monte Carlo calculation model is established and the statistical properties of projectile target deviation are computed. According to these deviation properties, another Monte Carlo calculation model is used to solve the hit probability and damage probability. Finally, some typical examples are presented to illustrated the proposed algorithm.
