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 an GPRs. The system is scalable at low-cost to accommodate multi-antenna multi-static testing for subsurface tomographic imaging.
Claims20
An impulse ground penetrating radar (GPR) system, the GPR system comprising:
- a transmitter antenna for transmitting radar signal pulses;
- a pulser for pulsing the transmitter;
- a receiver antenna for receiving the reflected transmitted signal pulses;
- a sampling receiver for digitally sampling the reflected signal pulse;
- and
- a signal generator for synchronizing the pulser and the sampling receiver.
A method for operating a ground penetrating radar, the method comprising:
- pulsing, a transmitter to emit a radar frequency electromagnetic wave;
- receiving a reflected component of the emitted wave, wherein the reflected component comprises a pulse time and idle time;
- digitally sampling the reflected component during the pulse time;
- and
- not digitally sampling the reflected component during the idle time.
An impulse ground penetrating radar (GPR) system, the GPR system comprising:
