To the problem that the anti-submarine needs hovering detection in submarine searching with dipping sonar,we planned a flight path for the anti-submarine helicopter hovering detection based on the hovering detection flight process,the shortest flight path standard and the geometric principle with consideration of the impact of wind on flight status.Analysis was made to the flight paths,and the mathematical model of hovering detection flight was presented.The flight path of single-helicopter round call-search was simulated based on the mathematical model. The simulation results show that hovering detection flight mathematical model can simulate more realistically the actual flight path of anti-submarine helicopter when searching submarine with dipping sonar.
