摘要：
The stepped-frequency continuous wave (SFCW) ground penetrating radar (GPR) combined with wideband bow tie antennas and a handheld VNA is successfully demonstrated and compared with three types of commercial pulse GPRs for the detection and identification of the buried targets at depths of 20 cm and 80 cm. It has the performance of the better signal to clutter ratio than all of the tested commercial pulse GPRs for the metal pipe at a depth of 20 cm and also the better range and azimuth resolutions than the pulse GPR having a center frequency of 250 MHz. It is strongly expected to be simultaneously satisfied with the conflicting needs of both deeper penetration and higher resolutions and to be finally replaced all of the tested pulse GPRs.
