中文摘要：
针对磁探仪应召螺旋搜索的特点,运用随机搜索理论定量分析了反潜巡逻机利用磁探仪进行螺旋搜索时的搜潜效能。根据飞行气象学中风对飞行影响的描述,结合潜艇运动规律的特点,建立了反潜巡逻机使用磁探仪执行螺旋搜索时的航路模型,并以反潜巡逻机与潜艇初始位置、反潜巡逻机航速和航向、风速和风向等为条件,经蒙特卡罗仿真分析,得到了潜艇速度已知和未知条件下,磁探仪搜索概率、搜索时间随潜艇位置散布和潜艇速度变化的情况。该航路模型既考虑了反潜巡逻机机动性能的限制,也考虑了海洋环境对反潜机的影响,较好地符合实际作战环境,满足磁探仪应召搜潜训练的要求。
英文摘要：
Based on the characteristics of Magnetic Anomaly Detector （MAD） call helix search, stochastic search theory was used for analyzing the search efficiency of it quantitatively. According to the influence of wind to flight described in flight meteorology and the characteristics of the submarine movement, the route planning model of the antisubmarine aircraft taking helical search with MAD was established. On the basis of the model, the varying of search probability and search time with submarine distribution and submarine velocity was obtained by Monte Carlo simulation when the submarine velocity was known or unknown, which was based on initial position of the antisubmarine aircraft and submarine, velocity and course of antisubmarine aircraft, and velocity and direction of wind etc. Both the maneuverability limit of the antisubmarine aircraft and the oceanic environmen＇s effect on the aircraft were considered in the route planning model, which is in accordance with the actual battle environment and satisfies the training of MAD.
