SAR image enhancement by dominant scatterer removal

In the paper the effective method of SAR image enhancement is presented. A strong scatterer produces sidelobes in range and cross-range dimension forming characteristic cross-shaped pattern centred on dominant scatterer. The presence of these sidelobes decreases the overall image quality and can mask weak scatterers close to the strong one. The proposed method is based on adaptive removal of modelled strong scatterer echoes from raw radar data. After removal the raw radar signal is reprocessed, and strong scatterers are then added to the final image. The method has been tested both using simulated and recorded data, showing its great potential.
