The underwater rocket is a new type of high speed weapon. Due to the high technology of the new weapons, and deficiency of the related information, it is difficult to identify the causes which occur to attacking ballistic trajectory. Based on the MonteCarlo principle, a mathematic simulation method was proposed, and the evaluating method of the simulation result was given by processing statistically the hit points of rocket. Based on recurrence of the representative attacking ballistic trajectory, the validation and availability of the method were demonstrated. The scientific explanations and efficient solutions to the possible problems on the rockets were also given, which greatly reduced the development risk of this product.

水下火箭是一种新型高速水中兵器,由于新武器技术跨越大相关型号信息缺乏等因素的制约,使得其超高速大变深的水下攻击弹道出现的一些现象、问题难以得到很好的解释和定位。基于蒙特卡洛法的数学思想,设计了一套数学仿真方法,并根据对模拟弹着点的统计学处理给出了相应的仿真效果评判办法。通过对某水下火箭典型攻击弹道的复现,验证了本方法的有效性和可行性。同时也对产品出现的问题给予了科学的解释及有效的定位,降低了产品研制的风险。
