The 3D multi-beam imaging sonar is an advanced underwater acoustic detection device that enables real-time 3D imaging and target recognition of underwater objects. Adopting broadband signal modulation technology, the device reconstructs underwater spatial information at the receiving end through an adaptive beamforming algorithm. It has a field of view of up to 45°×45° and an operating range of ≥50 meters, capable of accurately characterizing the geometric features of underwater objects.

  The system mainly consists of a transmitting transducer, a receiving transducer, an electronic cabin, and software. The upper part of the front panel of the electronic cabin is the transmitting transducer, and the lower part is the receiving transducer. The power supply and communication cables are led out from the rear end of the electronic cabin to transmit data to the shore-based computer.

  The 3D multi-beam imaging sonar device can significantly improve underwater operation efficiency. It is suitable for application scenarios such as port security and underwater structure inspection, and can meet the user needs for underwater target observation on various manned and unmanned platforms.
