Abstract
In the side scan sonar method, use is made of the back-scattering, at low grazing angles of incidence to the seabed, of relatively high-frequency acoustic waves radiated in a fan-shaped beam from a transducer contained in a towed body. The fan beam is oriented so that the wider angle is in the vertical plane (scan range) and the narrower angle in the horizontal plane (beam width) with the axis of the beam normal to the ship track. The display of the returns is usually realized as a series of closely spaced intensity-modulated lines on a paper recorder or computer screen display. In this way a two-dimensional picture of the seabed is build up. The adjacent imageries are overlapped in case that the survey track line interval is narrower than scan range. The improved method on seafloor sonar image mosaic processing to separate the imageries of this smeared part and to get the high resolution mapping results is proposed.
