Abstract：
The embodiment of the invention provides an underwater target detection and recognition device and method. The device comprises a registration unit, a detection and recognition unit and at least two single-view side-scan sonars which are arranged on each side of an underwater carrier and have different scanning directions, the registration unit is used for carrying out image registration on single-view acoustic images collected by all single-view side-scan sonars on the single side of the underwater carrier for the same underwater target to obtain an image registration result; and the detection and identification unit is used for determining a detection and identification result of the underwater target based on the image registration result. According to the device and the method providedby the embodiment of the invention, the detection rate and the recognition rate of the underwater target are improved, the false alarm rate is reduced, meanwhile, the underwater target is detected and recognized for multiple times by one navigation path, the energy efficiency ratio of an underwater carrier is improved, and the cost is reduced.
