Abstract

The authors have developed a relatively inexpensive, experimental synthetic aperture radar (SAR) system which can be flown on small aircraft. The entire unit weighs approximately 360 lbs with most of the weight in the battery-power supply. The system cost is kept low by using a simple RF subsystem with an all-digital IF and commercial components for the chirp generation, analog-to-digital conversion, and digital signal processing. The system has been successfully operated from a truck and an aircraft and has exhibited a range resolution of 1.5 m and an azimuth resolution of 0.5 m. The system is described and images from the tests are shown
