Abstract

Within ORFEUS (Optimized Radar for Finding Every Utility in the Street) project a novel antenna system for a SFCW GPR has been developed for detection and location of buried utilities. The antenna system consists of two cavity-backed resistively loaded bow ties and has been designed to cover the frequency range from 100 MHz to 1 GHz with a reasonably high radiation efficiency. The characteristics of the whole system in terms of the impedance matching to the feeding line, radiation level from the individual antenna, parasitic coupling between the transmit and receive antennas and scattering from buried objects have been experimentally investigated in realistic scenarios for different soils.
