The paper deals with the propagation of electromagnetic waves in space and their scattering at objects of location of complex electrophysical structure and spatial confi guration of natural and anthropogenic character, based on widespread use and development of the most eff ective modern asymptotic methods of electrodynamics, development and use of modern computational methods. Based on the principles of the method of physical theory of diff raction, the probable characteristics of the scattered fi eld are determined. It is possible to obtain the solution of the diff raction problem in the form of the sum of components caused by diff erent diff raction phenomena. A common feature of these components in the quasi-optical wavelength range is their additive form of representation. In this case, each term of the sum is an integral of the oscillatory sources distributed on the fi nite surfaces of an arbitrary spatial confi guration. The complexity of the spatial confi guration of the targets causes the use of numerical methods as the basis for constructing a calculated methodology for evaluating radar scattering fi elds. Thus, the task of calculating (estimating) the integrals from oscillating sources distributed on fi nite surfaces of arbitrary spatial confi guration with the proposed accuracy with minimal computational cost becomes relevant. It is the development and algorithmic implementation of computational procedures for the estimation of diff raction components of diff raction fi elds that is the main scientifi c and practical task. Mathematical modeling of radar scattering fi elds of the quasi-optical range for the purposes of complex spatial confi guration is rational to be performed on the basis of the method of physical theory of diff raction, since all known mathematical models of such goals are either a simplifi cation or a consequence of this method. The idea of the nature of the scattering surface of a real target allows to obtain the expression of the components of the scattering fi eld in the form of a vector sum of integral terms, each of which is an integral of the function of surface excitation sources on a regular or specially selected region on the surface of the model. The energy characteristics of the scattering fi eld depend signifi cantly on the conditions of polarization interaction of the target, the transmitter and the receiver.
