  • Wideband Ground Penetrating Radar System and Method
    Publication number: 20190154826
    Abstract: An improved Ground Penetrating Radar (GPR) system is provided. The system advantageously employs full waveform digitization of a returning signal to significantly reduce the number of launch signals and allowing the amount of radiation emitted to stay within the limit set by the Federal Communications Commission (FCC), while producing a robust information detection signal. In addition, intermittent large latent-duty-cycle sampling employs a less expensive digitizer typically used in prior art GPRs. The system is scalable at low-cost to accommodate multi-antenna multi-static testing for subsurface tomographic imaging.
