Abstract
We present the results of studies of backscattering characteristics of extended inhomogeneous media using a passive-active complex of near-field radio-wave imaging. The complex includes an 8-mm wavelength radiometer, a focusing antenna system, and a system of illumination of studied objects by a wideband noise signal. This radiometric complex is intended for the formation of a high-resolution radio image of the internal structure of spatially inhomogeneous media explored at distances commensurable with the size of the antenna aperture. The system of radio-wave imaging can be used for medical and biological studies of a human body and detection of extended objects hidden under the surface of a medium not transparent for visual observation, but partially transparent in the operating wavelength range.
