Paper Abstract

This paper addresses the problem of deriving as much as possible information from the measurement at a single antenna position, or spatial point. To this end, an inverse scattering approach retrieving the dielectric permittivity profile as a function of depth from the frequency domain data is presented. The method is capable to locate subsurface objects and distinguish between them depending on their permittivity value compared to the background. The validity and high robustness of the method are demonstrated with the use of synthetic data obtained for layered dielectric media. Experimental verification has been performed in the frequency band of 1 to 4 GHz using vector network analyzer. The influence of operational frequency band on the radar characteristics is discussed.
