Abstract：Multi‐beam sonar system and side‐scan sonar system are two important tools for the exploration of seabed .Both of them use acoustic method and there are similarities and differ‐ences in their working principle .Their research progress is briefly introduced and the data pro‐cessing of the two systems is compared and analyzed .It has been recognized that the data pro‐cessing of multi‐beam sonar system focuses on the accuracy of data measurement ,w hereas the data processing of side‐scan sonar is mainly emphasized particularly on the image processing . The main methods for the data matching and fusing used currently between the two systems are summarized ,which include the feature fusion of the same name ,the matching fusion based on the SURF algorithm and the characters fusion .From the principle of data acquisition ,the data fusion methods are deeply analyzed .It is found that there exist some difficulties in the po‐sitioning of detector ,the distribution of single Ping data point and the data positioning between the Pings .Even after a certain treatment ,what collected by the two systems are not simple planar images .Thus ,there are still some difficulties in the data fusion of the two systems .
