Abstract

A ground penetrating impulse radar system provides three-dimensional images of targets. A moving array of transmitting (52a, 52b) and receiving (56a, 56b) antennas provides narrow beamwidths and high gain by real and synthetic aperture beam processing. Narrow pulsewidth impulse signals (72a, 72b) are utilized to obtain high resolution. Round trip lime is calculated for each three-dimensional pixel in a search volume (24), and is used to process three-dimensional imagery (96). Analog to digital conversion (82a, 82b) can be utilized, so all signal processing is accomplished digitally. The radar system is applicable to detecting small objects (30) near the surface by using very narrow pulses, and also can be applied to detect large, deep objects by wider pulses.
