Abstract: A pulse radar system for determining the subsurface structure of a medium comprising an electronics unit for providing electronic signals and control comprising a utility controller, a sampler controller, and a timing controller such that the timing controller provides a pulser trigger and the sampler controller provides a sampler trigger; a microwave unit comprising all the microwave components within the system including a pulser for generating pulses as directed by the timing controller in the electronics unit, a transmitting antenna for receiving the pulses directly from and being in close proximity to the pulser, a receiving antenna for accepting the pulses emitted from the transmitting antenna, and a receiver in close proximity to and for accepting the pulses from the receiving antenna, and a data unit for receiving signals from the electronics unit and for displaying the data for review and analysis.
