Synthetic Wideband Waveform for Ground Penetrating Radar Application

The synthetic wideband waveform (SWW) technique meets the high hardware requirements for the ultrawideband (UWB) signal construction. The main advantage of the SWW is the reduction of the instantaneous bandwidth and a sampling rate by the channelization of the wideband signal and relatively narrowband sub-pulses processing. In this paper, a stepped-frequency chirp and phase codes are utilized as a ground penetrating radar (GPR) probing sources. The feasibility of that proposal is examined by the finite-difference time-domain (FDTD) simulation.
