Paper Abstract

A new ground penetrating radar system was built using a controllable variable pulse-width transmitter and a new antenna design. The transmitter generates monocycle pulses with pulse widths that are continuously variable from 0.5 to 2 nanoseconds; thus, the center frequency of the pulse spectrum is variable from 500 to 2000 MHz. The antenna is relatively small and light weight and operates in both the air-coupled and ground-coupled mode. The complete prototype system, including radar control unit, antenna unit, lap-top computer, battery, and back-pack, weighs 65 pounds, is portable and easily usable by one person.
