Compared with single beam depth sounder,multibeam depth sounder can measure underwater terrain extensively with high precision. By outfitting a multibeam depth sounder on a small unmanned boat, it can easily measure water areas where manned boats are difficult to measure (eg small dams, reservoirs, rivers).This method can satisfy customers’request to efficiently grasp underwater terrain. In this paper, we introduce the small multibeam unmanned boat, the operating method and sample measured data.
