该文以风这一典型的随机过程作用为例 ,利用纵风作用下随机弹道系统成形滤波器 ,把成形滤波器的微分方程与外弹道角运动方程及质点弹道方程联立 ,便构成为易于求解的完整的外弹道随机动力学模型。在具体的数字仿真实施过程中 ,采用尾翼延时张开技术来减小散布的措施 ,利用经典的统计试验法——蒙特卡洛法得出了不同平均风速下的火箭弹角散布与尾翼延张时间的关系的仿真曲线。仿真结果表明 ,有色噪声的白化是完全可行的 ,同时也从实例中证明了成形滤波器理论的正确性 ;也得到在一定风速下的最佳尾翼延张时间 Taking the typical stochastic process of wind as an example, by using the stochastic ballistic system forming filter under the action of longitudinal wind, the differential equation of the forming filter is established together with the equations of the external ballistic angle and the particle trajectory equation, A Complete Model of Exterior Ballistic Stochastic Dynamics Solved. In the process of concrete digital simulation, the delay spread technique of tail fin was used to reduce the dispersion. By using the classical statistical test method - Monte-Carlo method, the distribution of rocket angle and the tail extension Simulation of the relationship between the time of the curve. The simulation results show that the whitening of colored noise is completely feasible. At the same time, the correctness of the forming filter theory is also proved from the examples. The optimum tail-wing extension time under certain wind speed is also obtained
