Abstract
Justification of electrodynamic model of the spreading surface developed taking into account influence of the spreading surface is given in article. The model is developed for application in problems of design of systems of collision with the earth and also at design of onboard radar-tracking systems. The comparative analysis of the following models is carried out: continuous, facet, based on Huygens-Kirchhoff's principle, in the form of the carrying-out hemispheres and semi-cylinders of identical radius randomly located on ideally carrying out plane. The theories developed for continuous surfaces can't be directly applicable to reflection from the land surface. Their strong sensitivity of dispersion to various properties of a surface doesn't allow to receive final formulas of dispersion, uniform and general for any surface.
