摘要：

A key factor for the accurate interpretation of surface-penetrating radar records is to know as much as possible about the transmission features of our antennas. The characteristics of the detected reflections (trace time zero, duration and shape of the reflected pulse, minimum overlap distance between direct signal and first reflection, etc) depend on the issued signal properties. Since these characteristics can vary for the different GPR equipments available, in this paper we present the results of various experiments to analyze and calibrate 500, 800 and 1000 MHz shielded antennas.
