Abstract

Radar remote sensing methods for exploration of different dielectric media may be highly efficient for obtaining the necessary information on media properties. In many practical cases, the operation of such systems is carried out either directly on the surface of the investigated media or for elevated antennas at some height (comparable with the wavelength) above the surface. In these cases it is necessary to take into account the influence of dielectric properties of the medium on the impedance characteristics of the transmit-receive antennas. The results of theoretical and experimental investigations concerning the influence of the dielectric properties on the parameters of dipole antennas situated near the surface are analysed. The possibility to determine the dielectric medium properties by means of a two-dipole antenna system is evaluated.
