This paper presents the hardware design, signal processing aspects and first trial results of a C-band Synthetic Aperture Radar (SAR) named SARENKA developed at the Warsaw University of Technology, Poland. The main goal of the presented work was to design a low-cost, small-size and low-weight C-band SAR radar dedicated for medium class unmanned aerial vehicles (UAV) and small aircraft. The developed system allows high resolution SAR images (up to 10cm) of an observed ground area in almost all weather conditions to be obtained. The high resolution in the range direction was obtained using the Frequency Modulation Continuous Wave (FMCW) mode. The high resolution in the cross-range was obtained using advanced SAR signal processing and autofocusing methods, which allow for good azimuth compression using low cost INS/GPS systems dedicated mostly for cheap amateur UAV platforms. The system was preliminary tested using a private car as a ground moving platform. The next step of the system tests will be trials with an ultralight aircraft.
