基于先验目标分布的磁探仪应召搜潜范围分析

根据磁探仪应召搜潜的特点，运用概率论和最优搜索理论对磁探仪应召搜潜的搜索半径进行研究。在建立目标初始位置的散布模型和目标航速航向模型的基础上，推导出磁探仪执行应召搜索时的搜潜概率解析模型，确定了搜索概率最大时的圆周搜索半径，建立了反潜巡逻机利用磁探仪执行应召搜潜时的航路模型。在不同条件下，利用解析模型计算得到的搜索概率与蒙特卡罗仿真结果基本一致；与传统的应召搜索方法相比，改进后的搜索方法能使搜潜效能得到明显提高。

Scope analysis for call search submarine of magnetic anomaly detector based on transcendental target distribution

According to the characteristics of call submarine-search with a magnetic anomaly detector, the optimal search scope is explored using probability theory and optimal search theory. On the basis of establishing the models of submarine initial position distribution and submarine speed and course, an analytic model of call submarine-search probability on the magnetic anomaly detector is derived, a radius of circle search making maximum search probability is obtained and the route model of antisubmarine patrol aircraft performing call submarine-search is established. The search probability by simulation with Monte Carlo is basically consistent with that of by computation with the analytic model. Also, the search submarine efficiency is improved clearly compared with a conventional call search.
