Monte Carlo ballistic simulation applied to dispersion analysis of starting control points for Antitank Missile

摘要

This paper provides an overview of the Antitank Missile Monte Carlo starting control points dispersion analysis conducted with the ballistic simulation. First, The disturbances that affect the flight of a missile are analyzed. Then a method of how to handle with the disturbances is presented to establish a ballistic simulation model with Monte carlo method, the steps of simulating the disturbances based on Matlab are also given. Taken account of the initial angular rates disturbance, rocket engine thrust misalignment, wind disturbance, the equation that described the dynamics of the missile mass center movement should be adjusted accordingly. In this paper, a common model is established to simulate the effect of disturbances. Results indicate that missile trajectory disturbances could be substantially reduced by lowering rocket engine thrust misalignment.
