Problems solved by technology

The multi-line array is difficult to retract and deploy, and it is not convenient for ships to maneuver; the vector array still has a series of complex physical problems that cannot be solved well
Aiming at the ambiguity problem of starboard and starboard sides existing in a single scalar hydrophone linear array, the present invention proposes a curved hydrophone array that can distinguish starboard and starboard sides, which has significant application value

Abstract

The invention discloses a curve type scalar hydrophone array capable of distinguishing a port side and a staboard side. The curve type scalar hydrophone array comprises a curve type array unit provided with an outside-array signal transmission cable and a tail rope, wherein the curve type array unit comprises a sleeve tube, wherein the two ends of the sleeve tube are closed and are bent to form acurve shape; the sleeve tube is internally provided with an in-array signal transmission cable, a plurality of scalar hydrophone elements and a plurality of attitude depth sensors; and the plurality of scalar hydrophone elements and the plurality of attitude depth sensors are uniformly distributed and arranged along the length direction of the sleeve tube. According to the array, the port side andthe staboard side of a target can be distinguished only by using one scalar hydrophone array, and the advantages of being low in cost, free of influence on the maneuverability of the naval vessel andthe like are achieved.

Description

technical field [0001] The invention relates to underwater acoustic detection technology, in particular to a curvilinear scalar hydrophone array capable of distinguishing starboard and starboard sides. Background technique [0002] A hydrophone is a sensor that uses sound waves propagating in the ocean as an information carrier to detect underwater targets, locate, identify, track, and realize underwater navigation, measurement and communication. Hydrophone technology is widely used in all aspects of naval underwater activities, and is the main means of ship detection, reconnaissance and navigation. Due to the requirements of underwater military defense and the urgent need of human beings to develop and utilize marine resources, hydrophone technology has achieved unprecedented development. [0003] In order to improve the detection distance and accurately locate and orient the target, hydrophones usually need to form an array for target detection. Among them, the line arra...
