Description
Summary:Three-dimensional imaging of sonar has important application in the fields of precise navigation and target recognition. In the paper, we describe an efficient model to compute the backscattering sound of high-frequency from complex underwater target for simulating the 3D image based on sidescan sonar. The target we used is the Generic submarine model which was designed by German FWG workshop. The Kirchhoff approximation formula is derived and the 3D model of the Generic submarine is constructed by graphics software. To verify the model, the target strength of the submarine model predicted by our method has been compared with that given by Generic BASIS and produces a good fit. The imagining technology of the sidescan sonar is discussed and high resolution 3D image of the sidescan sonar is obtained.
