Abstract
Remote sensing using unmanned aerial vehicles is gaining more and more importance during peace keeping missions for military reconnaissance. Those applications nowadays have to take into account that under civil war conditions a mix-up of sensors within sensitive urban terrain may be useful. These tasks typically have to be fulfilled also under adverse weather conditions, which mainly can be served by airborne imaging radar sensors. Advanced radar sensors are able to deliver highly resolved images with considerable information content, as polarimetry, 3d-features and robustness against changing environmental and operational conditions. Extending the knowledge base for an object by fusion of radar data with Ladar-information or IR, a safe detection and even identification of objects becomes feasible allowing an optimized signal processing by distributing the assignments between the combined sensors. The contribution describes the different sensors and gives an overview over the image data for the sample scenes. The methods of object discrimination are discussed and representative results are shown.
