To improve the search submarine efficiency of on-call spiral search submarine by antisubmarine patrol aircraft with magnetic anomaly detector(MAD),the optimal circle search radius is explored by using probability and optimal search theories.Considered the distribution characteristics of the submarine's initial position,speed,course,and so on,an analytic model of search probability on MAD circle search is established,and the circle radius making the search probability maximum is derived.Based on the air line simulation algorithm,considered the maneuverability of patrol aircraft,a mathematic model of route planning for the patrol aircraft to search submarine in spiral is established,and the search efficiency is simulated and analyzed with Monte Carlo method.The simulation results show that the search probability is basically identical to the calculation result by using analytic model and the search efficiency is improved obviously.
