摘　　要：针对舰载反潜直升机协同实施前置搜索的发现概率计算问题,在分析多机吊放声纳前置搜索方法特点的基础上,采用解析的方法,从前置搜索任务参数、兵力数量、搜索时间、吊放声纳平均搜索周期与搜索速度等方面,建立了舰载反潜直升机前置搜索发现概率计算模型,给出了吊放声纳探测区域重叠下的有效搜索面积计算方法。仿真计算了前置搜潜区宽度、兵力数量、间距系数、搜潜转向角等因素影响下的发现概率,并得出:搜潜区宽度一定时,存在最佳间距系数和最佳搜潜转向角使得发现概率最大;双机协同前置搜索效能显著高于单机等。Aiming at the search probability calculation,the characteristics of multi-helicopter preposition search using dipping sonars are analyzed.Adopting analysis method,the model for calculating preposition search probability is built,which considering the task parameters,helicopter number,and search time,mean search cycle and search velocity of dipping sonar.The calculating method of effective search area is given,which deals the overlap area of dipping sonar detection range.It simulates search probability with different parameters of width of preposition search zone,helicopter number,spacing coefficient,and steering angle.Results show that it can get the maximum search probability with the optimum spacing coefficient and optimum steering angle when given the width of preposition search zone;the probability of two helicopters cooperating preposition search is higher observably with single helicopter.
