摘要： Apparatus for determining the position in azimuth of a surface vessel, with respect to an underwater sonar signal source, irrespective of the motion of the surface vessel, comprising a hydrophone, capable of determining the azimuth of an underwater sonar signal source with respect to the roll and pitch axes of the surface vessel, and a universal joint, connecting the hydrophone to the surface vessel, its two axes of rotation being parallel to the roll and pitch axes of the surface vessel, thereby effectively permitting the hydrophone to rotate about the roll and pitch axes of the surface vessel. A vertical reference, attached to the hydrophone so as to pitch and roll with it, comprises a roll sensor and a pitch sensor for determining the roll and pitch, respectively, of the hydrophone. A roll summer and a pitch summer, whose two inputs are the outputs from the hydrophone and the roll sensor and pitch sensor, respectively, serve to determine the true azimuth of the sonar signal source, with respect to the roll and pitch axes of the surface ship, in spite of any roll or pitch of the hydrophone, or of the surface vessel.
