Due to the influence of complex underwater acoustic channels, the image generated by side scan sonar have problems such as low resolution and blurred details, which brings some difficulties to the small target detection and recognition process based on side scan sonar images. The common image super-resolution processing algorithms can be roughly divided into interpolation algorithm, sparse representation reconstruction algorithm, etc. The traditional interpolation algorithm has the problems of blurred image edges and unclear details. This paper proposes an improved super resolution generation countermeasure network (SRGAN) structure. This structure can improve the display of detail features on the basis of retaining the details of small targets in the image, and make the target edges clearer, which can provide technical support for the subsequent small target detection and recognition to a certain extent.
