摘　　要：随机风是影响火箭弹落点散布的一个重要因素。将风场作为典型的随机过程,建立随机风场的工程化数学模型并结合火箭弹被动段动力学运动方程,利用经典的统计试验法——蒙特卡罗法进行随机风作用下火箭弹落点散布的仿真,预测弹丸落点。通过仿真,得出各个表征风场性质的参数对火箭弹落点散布的影响结果,有效分析随机风对火箭弹落点散布的影响,为提高火箭弹射击精度、减小落点散布、进行弹道修正提供实验依据。Random wind is one of the important factors causing the shell distribution of rockets. Random wind is regarded as typical random process and the engineered model of that is established which is made into the dynamics equations of the rocket passive trajectory, so that the traditional statistical analysis approach-Monte-Carlo method is applied in shell distribution simulation and prediction rocket impact point under random wind. Through simulation, the effect resuits of all parameters characterizing the nature of wind on rocket shell distribution are obtained and effect of wind on the rocket shell distribution is analyzed effectively in order to provide the experiment data for increasing the firing accuracy of the rocket, decreasing the shell distribution of the rocket and trajectory correcting.
