Description
Summary:A new universal 3D scalar and vector modification to the method of discrete sources (MMDS) for the numerical calculation of the scattering pattern of the body of revolution is described. To illustrate the use of the developed technique, the scattered field of the spheroid and multifoil of revolution are calculated. It is shown that analytical transformation of the scatterer's surface and wavelet technique allows creating an efficiency algorithm with rather small time of computation.
