This paper introduced the method of cross manoeuvre anti-submarine blockade of submarine carry out.The factor of probability of anti-sub submarine detecting submarine is simulated ang analysed by Monte Carlo Simulations.We got the conclusion that detecting probability is deeply affected by moving velocity and manoeuvre depth of anti-sub submarine and detecting distance of sonar.Breaking point exist.Based on the results,this paper analyse the advantage and disadvantage of cross manoeuvre and vertical enemy courses under different condition.%介绍了潜艇实施交叉机动反潜封锁的方法,通过采用蒙特卡罗方法对反潜潜艇交叉机动发现敌潜艇概率的因素进行仿真分析,得到了“实施交叉机动反潜封锁发现潜艇的概率受反潜潜艇速度、声呐探测距离、机动纵深影响明显并存在突变点”这一结论,以此为基础分析了交叉机动与垂直敌航向往返直线机动反潜封锁方法在不同使用情况下的优劣.
