A hydrophone arrangement, housed within a dome shaped concrete and steel bunker, to accurately establish a bearing of a target object while diminishing potential displacement of the hydrophone arrangement from an initial installed position. A plurality of hydrophones are centrally positioned within the bunker and equally spaced about a periphery of a steel cylindrical member so that each hydrophone receives acoustic energy in a time delay manner with respect to the other adjacent hydrophones so that a bearing determination may be made from information received by a single stand alone bunker. An acoustic horn may also be provided to focus the acoustic energy towards the hydrophones to improve the signal-to-noise ratios and provide control of the phase of the acoustic energy as the energy is received by the hydrophones.

[ What is claimed is:] [1.] A hydrophone arrangement, for determining a bearing of a target object relative to said hydrophone arrangement said hydrophone arrangement comprising:a central solid mass support member supporting a plurality of hydrophones about an exterior periphery of said solid mass support member, each of said plurality of hydrophones being directly exposed to a transmission medium, and each of said plurality of hydrophones being located about the exterior periphery of said solid mass such that, during operation, each hydrophone is able to receive directly acoustic energy propagating through the transmission medium in a time delayed manner thereby providing a mechanism for said hydrophone arrangement to supply information to calculate the bearing of said target object solely by acoustic energy received by said hydrophone arrangement;wherein said hydrophone arrangement is housed within a bunker which has a roof portion and a base portion, and said plurality of hydrophones are located between said roof and base portions so that, during operation, each of said plurality of hydrophones is directly exposed to the transmission medium and is able to receive directly acoustic energy propagating through the transmission medium; andsaid hydrophone, upon directly receiving the acoustic energy propagating through the transmission medium, calculates both the bearing and the distance of said target object relative to said hydrophone arrangement.
