The effective method for the calculation of the acoustical field scattered by the spatially-localized smooth surfaces in weakly inhomogeneous media was developed. The method based on the solution of the problems of aiming the connected rays and calculation of the rays intensity by analytically determined curvatures of the transverse sections of the beams. The results of numerical calculation of the scattered field structure for the different displacements and orientations of the ellipsoid in the refractive layered medium are represented.
