Abstract

The invention discloses a sonar target detection method based on the Faster R-CNN. According to the method, characteristic extraction is performed on targets in different complex underwater environments through utilizing the deep learning technology, the method is the major innovation and attempt compared with present sonar target detection methods, limitations of traditional methods are broken, deep characteristics of sonar images at the low SNR can be extracted, and good target detection and identification on the linear targets can be carried out. The sonar target detection and identification network based on the regional accelerated convolutional neural network (Faster-RCNN) is established to carry out target detection for sonar data. The method is advantaged in that good performance oflinear target detection of the sonar images is achieved, feasibility of the deep learning method in sonar target detection is verified, and a new research method is provided for characteristic extraction of the complex underwater acoustic environment data.
