Abstract :
COASTSYSTA has developed a 3-dimensional target strength model of an arbitrarily shaped object based upon an application of the Kirchoff approximation and the geometric theory of diffraction. A comparison between theory and experiment is made for several scale model targets. In addition it is shown how this target strength model can be incorporated in a sonar performance prediction model to generate synthetic images of proud targets. Synthetic images for both real aperture and synthetic aperture sonars are presented, and the effects of multipaths on shadows are discussed
