A method is proposed for calculating the secondary radiation characteristics (SRCs) of resonance perfectly conducting objects located in free space. The method is based on the solution of the magnetic-field integral equation and ensures elimination of resonances that are due to the eigen oscillations of the interior region of a perfectly conducting object and that appear as a consequence of numerical implementation. The calculated scattering characteristics of perfectly conducting objects of simple shapes (a sphere, a cylinder, an ellipsoid, a disk, and a cube) are compared to data of physical simulation and to results obtained with the help of other calculation techniques. The peculiarities of calculation of the scattering characteristics of the considered objects, including impulse responses, are analyzed. The parameters of the computational algorithm for calculating the SRCs of objects of complex shapes are determined with the use of the data obtained for model scatterers.
