Diagnostics of Layered Medium Parameters: The Influence of Vector Space-Time Time Response of Transceiving Antenna

Electro-physical restoration of layered medium parameters is considered. The method is based on UWB electromagnetic sounding of the medium, scattered field reception, transceiving antenna influence compensation, and estimation of medium reflection function. The method includes: measurement (or numerical calculation) of electric field component on the plane surface close to the transmitting antenna; field approximation by the superposition of elementary E and H plane waves; determination of antenna vector effective height; estimation of sufficient number of plane waves which is necessary for finding reflection function of the medium; transformation of scattered field back to the receiving antenna port. The accuracy of electromagnetic field approximation by the limited number of plane waves is investigated.
