Measurement and evaluation results on signal processing algorithms for low frequency Synthetic aperture radar.

The presents summarizes a selection of my research within Synthetic Aperture Radar (SAR). Mainly the research is aimed at applying and developing signal processing methods to single channel and multi channel SAR for wideband systems. SAR systems can generate images looking very similar to optical pictures, i.e. photos, and sometimes with much finer resolution compared to optical systems orbiting Earth. In the presentation, SAR systems capable of very high resolution imaging are considered, and data from such systems, namely the VHF system CARABAS-II and the UHF system LORA, is used. The topics in the presentation are related to detection and parameter estimation of moving targets in SAR. Images with results illustrate the strength for the algorithms.
