The bow-tie antenna, which is widely used in impulse ground penetrating radar (GPR), has very low radiating efficiency. It is because that, nearly 70% of the radiated energy exists as the form of end reflection, which is harmful to probe objects. In order to keep the probing ability, the remarkable energy in end reflections is usually dissipated by resistive loading. We find that, in this paper, if...
This paper proposes a new method of integrated system calibration that uses the transmitting and receiving signals from the impulse ground penetrating radar itself. In order to eliminate the influence from each subsystem or part including antenna, transmitter, receiver, signal processing circuits and transmission cables, two new calibration parameters that are different from the conventional S-parameters...
