Abstract

The invention provides a multi-beam sonar array comprising an electronic compartment housing, a transducer array, a sonar housing, an acoustic transmission cover and an O-shaped sealing ring. The electronic compartment is used for placing electronic equipment and is connected with the sonar housing in a sealing manner. The transducer is a transceiving integrated piezoelectric ceramic acoustic unitand is installed at the sonar housing. The sonar housing has a structure formed by combination of a cylindrical section shell and a hemispherical shell; and the cylindrical segment shell is divided into several layers and each layer contains a plurality of elements. Electronic wave beam scanning is performed on the horizontal plane to realize detection of a small target in a 360-degree horizontaldirection within a certain vertical included angle range. According to the invention, because of the high-resolution image sonar with the small target as a detection object, detection of the small target in a 360-degree horizontal direction within a certain vertical included angle range is realized.

Description

technical field [0001] The invention relates to the technical field of underwater small target detection, in particular to a multi-beam sonar array. Background technique [0002] At present, small underwater targets such as AUVs and frogmen have become the protagonists of shallow sea invasion, port penetration, oil field destruction, directional guidance, terrorist attack destruction and local conflicts. It has the advantages of strong maneuverability, target echo and its own radiation characteristics are not obvious. Foreign countries have vigorously developed various near-shore operations and equipment, established underwater operations, infiltrated frogman troops, developed surface and underwater unmanned combat platforms, and advanced frogman transportation devices. Therefore, deploying sonar detection equipment in important waters to detect, locate, identify, and track intrusion targets is an important means to combat threats such as underwater frogmen, vehicles, and u...
