The present paper proposed the results of numerical experiments based on the classical theory of electrodynamics but it has practical importance in radiolocation and radio-spectroscopy at specific laboratorian and technological conditions. There is investigation the structure of the scattered electromagnetic field of a linearly or circularly polarized incident wave with frequency ω on the surface of an ideal conductive sphere with radius \( {\text{a}} \) in the condition \( \lambda \gg a \) (\( ka \le 1) \), where \( \lambda \) is the wavelength of the incident wave. The general equations for the scattered field and Poynting vector, both directly near the conductive sphere and in the far zone (Fraunhofer zone) from the scattered object are analytically received. Using computer simulation there are obtained vector diagrams for the components incident and scattered electromagnetic waves, the structure 3D Poynting vector and total electromagnetic field on the surface of a small spherical conducting object located near the antenna system. In spite of the fact that the influence on the fields at the receiving point from separate small objects is negligible, should be mentioned that under certain conditions with a lot of obstacles they can affect the summary field at the receiving point. Therefore, studying the field structure on the surface of a scattering objects is great importance.
