Synthetic aperture radar (SAR) provides information different from those gathered by optical sensors and it acquires data day or night regardless of cloud cover through the microwave spectrum. The SAR processing system is an essential requirement in every ground station in order to properly interpret and fully utilize the information contained in these data sets. This paper describes the processing algorithms that generate images from the SAR signal and proposes the application of SAR ground station development to satisfy such requirements. A SAR ground system is implemented using those algorithms. It generates SAR image products according to processing levels. Experiments conducted in this paper show results comparable to the commercial SAR processing software.

Abstract In the paper experimental results of ISAR (Inverse Synthetic Aperture Radar) processing obtained with highresolution radar are presented. Targets under observation were ground moving vehicles, such as cars, trucks and tractors. The experiments were performed with a FMCW (Frequency- Modulated Continuous-Wave) radar operating at 94 GHz with almost 1 GHz of bandwidth. Due to the measurement scenario more typical for SAR (Synthetic Aperture Radar), than ISAR, i.e. targets moving along straight line crossing the antenna beam, algorithms usually applied for SAR processing have been used.
