ABSTRAKT

Phase structure of signals, synthetic antenna aperture and signal polarization relating to the Stepped Frequency Continuous Wave (SFCW) GPR sensor is being analyzing for purpose of landmine detection and recognition. The phase structure is obtained from signal phase-frequency spectrum on an output of the quadrature phase detector of SFCW GPR. It was shown that combination of synthetic antenna aperture and signal phase structure allows a landmine to be detected and their main physical properties (metallic or dielectric) to be recognized. A special antenna that allows to transmit signal on two cross polarizations and to receive the full signal polarization matrix have been developed for purpose of signal polarization selection capable of a nonsymmetrical object recognition. It were used two developed SFCW GPR sensors operating at the frequency bands of 140 - 270 MHz and 550 - 850 MHz for testing the developed signal processing algorithms in natural field and laboratory conditions.
