Study and Implementation of the Methods of the Side-scan Sonar Image Processing

With the increasing of side-scan sonar applications, the studies on side-scan sonar image processing have been reported more and more increasingly. This paper firstly analyzes these current studies in this field to explain the need for this study, then it brings forward the main contents of side-scan sonar image processing and analyzes these contents one by one. Based on SIS-1624 side-scan sonar system, ArcGIS92 and Oracle92 this paper has built a prototype system and implemented the geometric correction, the gray correction, the geo-coding and the image fusion methods.
