ABSTRACT

The model of scattered electromagnetic field in the region of their receiving for solving problems of the earth's remote sensing is proposed, using phenomenological approach based on the geometrical optic laws and the Huygens-Fresnel principle. The procedure for image processing, while restoring the coherent radar image of the earth's surface in the near-field zone is shown. The obtained image structure is described by the convolution integral of the complex scattering factor with the radar system ambiguity function. Noted, that due to the complex internal structure of the scattering factor, it is reasonable to consider the field in the receiving region not only as the Riemann integral, but also the Lebesgue and Stieltjes integrals, and the Ito stochastic integral.
