目标散布已知情况下鱼雷发现概率计算方法

摘要

When probability density of target is known,according to the searching means and moving search trajectory of acoustic homing torpedo,calculate the relative trajectory to the center of target distributing area,using the principle of calculus,calculate the integral range through simulation,the probability density function is integrated by numerical method,thus the find probability is gained.%在目标散布概率密度已知的情况下,根据声自导鱼雷的搜索手段和机动搜索弹道,计算其相对于目标散布中心点的相对弹道.利用微积分原理,通过仿真方法计算积分区域,并对被积函数进行数值积分计算,求解声自导鱼雷机动搜索弹道发现目标的概率.
