Abstract

In this study, we propose a new method for the imaging simulation of looking forward sonar. According to the theory of acoustics, the Kerchief’s integral formula is used to solve the scattering sound field of objects in the water and the models of objects are set up. Secondly, the surface of objects is divided into some parts and the formulas are proposed to gain echo data according to the reflecting condition of those parts. These data are used to generate sonar images of objects. At last, the simulation results of echo data and sonar images are contrasted with those gained from the water tank test. The results verified the feasibility of the new method.
