Research on optimization selection of anti-submarine aircraft course in aero-magnetic exploration

To solve the problem of optimal course of anti-submarine aircraft in the process of searching submarine using magnetic detector, three indexes and a method for evaluating the ability of anti-submarine aircraft searching submarine by magnetic detector with different courses are proposed, on the basis of modeling and analysis of submarine magnetic field. Then the ability above is simulated and analyzed, and the result shows that the anti-submarine aircraft has the best detection effect along the north and south direction, and the worst detection effect along the east and west direction.
