摘要
利用悬浮式深弹拦截来袭鱼雷时,要在鱼雷可能来袭的航路上布设多枚深弹组成拦截线,以提升对鱼雷的毁伤概率。传统布设方法基于对鱼雷探测误差和深弹毁伤半径,确定目标可能通过区间并均匀配置深弹,没有合理地基于深弹射击误差和预定毁伤概率,确定深弹布设数量和瞄准点。基于预定概率区域射击方法以毁伤概率为预定指标,同时考虑观测误差和射击误差的最优拦截模型;通过构建中间函数求取理论最优毁伤概率,再根据最优毁伤概率,将预定毁伤概率作为输入,迭代求解布设深弹数量。通过分析拦截策略确定深弹布设瞄准点。仿真结果表明:该方法可以基于预定毁伤概率快速得到最优射弹数和瞄准点,验证毁伤概率与预定毁伤概率的误差小于1%,实现了水下拦截线的精确布设。
When using hovering deep bombs to intercept incoming torpedoes,multiple deep bombs are deployed along the possible torpedo path to form an interceptor line,thus increasing the probability of damaging the torpedo.The traditional deployment method is based on the detection error of the torpedo and the radius of destruction of the deep shells.It determines the probable passage interval of the target and distributes the deep shells evenly.However,the traditional method does not take into account the firing error of the deep ammunition or allow for a reasonable number of deep ammunition deployments and aiming points based on a predetermined damage probability.To address this,an optimal interception model is constructed by taking the destruction probability as the predetermined index,considering both observation error and firing error.By constructing an intermediate function,the theoretical optimal damage probability is obtained,and the predetermined damage probability is used as input for iteratively solving the number of deep bombs to be deployed based on the optimal damage probability.Finally,the targeting point of deep bomb deployment is determined by analyzing the interception strategy.Simulation calculations show that this method can quickly obtain the optimal number of projectiles and aiming points based on the predetermined firing probability.The error between the verified damage probability and the predetermined damage probability of the scheme is less than 1%,achieving the accurate deployment of the underwater interception line.
