The recent interest in the potential of ultra-wideband (UWB) radar techniques has given rise to many fundamental questions on the relative merits of UWB versus more traditional radar designs. SRI has been actively engaged in the use of UWB radar for a variety of applications, including ground-penetrating synthetic aperture radar. Synthetic aperture radar (SAR) techniques are a convenient way of obtaining meaningful images from radar return signals, and the UWB/SAR combination may prove to be a powerful tool for imaging buried mines and mine fields. This paper discusses the results of a project to use a UWB/SAR to image buried mines. The UWB/SAR technique is explained briefly and experimental results are presented.
