Abstract: For analyzing the effect of the call distance on the detecting probability in call magnetic anomaly searching submarine, the model for calculating the submarine distribution probability was deduced, and then the relation between the call distance and the call magnetic anomaly searching submarine probability was established. At last, some calculation results were given out for some typical cases. The results show the call magnetic anomaly searching submarine probability descends rapidly with the call distance increasing, just only in near call distance, small initial distribution radius and low velocity, the call magnetic anomaly searching submarine has a high detecting probability. This shows that the call distance has a serious effect on the detecting probability in call magnetic anomaly searching submarine, and the magnetic anomaly detecting is not fit for searching submarine for far call distance.

Key words: searching submarine probability, call searching submarine, call distance, magnetic anomaly searching submarine, distribution probability

摘要： 为了分析应召搜潜过程中通报距离对搜潜概率的影响,推导出了计算潜艇位置分布概率的模型。通过该模型建立了通报距离与应召磁异搜潜概率的关系,并给出了一些典型情况下的计算结果。结果显示：应召磁异搜潜概率随通报距离的增加迅速下降,仅当通报距离较近且潜艇初始分布半径较小、航速较低时,应召磁异搜潜拥有较高的探测概率；从而表明通报距离对应召磁异搜潜概率影响较大,磁异探测不适合对远的通报距离的区域实施搜索
