Abstract. The mathematical model of radar objects scattering characteristics with complex electrophysical structure and shape containing impedance wedge-shaped structures is presented. Formulas for equivalent edge currents definition, based on the modified Ufimtsev’ diffraction coefficients and Malyuzhinets theory are shown. Ufimtsev’ functions angular distribution for field from non-uniform currents and radar cross section (RCS) calculation for the impedance cylinder are shown. A comparison of RSC angular distributions with rigorous integral equation method is produced.

Keywords: physical theory of diffraction, impedance wedge, polygonal model, scattering.
