In this article the development of the physical theory of diffraction for backscattering from an impedance wedge is described. It is shown that in the case of impedance boundary conditions Ufimtsev’s function f0(g0), which determines the diffraction field from the uniform current must be multiplied by the reflection coefficient from the corresponding face of the wedge, and the function f(g) for the total diffraction field must be changed by the G.D. Malyuzhinets’ diffraction coefficient. The wedge backscattering diagrams obtained with the use that theory are presented, and the comparison with calculations based on the Malyuzhinets’ theory are presented. The angular diagrams of the function f1(g1), which determines the diffraction field produced by the non-uniform part of the current are obtained.
