Abstract
This paper describes a small UAV-based SAR using low-cost 5–6 GHz radar, GNSS/RTK and IMU sensors for generation of high-resolution images. Measurements using straight as well as highly curved flight trajectories show range and cross-range lobe widths close to the theoretical resolution limits. An analysis of the improvements given by the use of attitude data is included.
