Abstract:

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.
