Abstract
Synthetic aperture radar (SAR) as a method for ground imaging by using a single antenna or a sensor array has widely found attraction for remote sensing applications and reconnaissance tasks. Independent of the particular sensor but inherent to the SAR processing, moving objects in the observed scene will be imaged at wrong positions and can appear in a smeared fashion. To avoid these disturbing artifacts in the image, a joint spatial-spectral filtering approach is proposed in this paper that allows to suppress signal contributions from moving targets in multi-channel radar data. Results obtained with experimental data from an airborne system show the potential for a practical application of the presented method.
