The Research of Using Towed Linear-Array Sonar to Hunt Submarine by the Surface Warship Formation

The towed linear-array sonar has better detecting capability and invisibility.The surface warship has definite blind angle ahead because the towed linear-array sonar takes passive detection and other technical limit.Aiming at this problem,this paper analyses the method to offset blind area,and then,puts forward station and using method of three ships to offset blind area.This method has better maneuverability and can advance hunting efficiency to submarine.
