The Spaceborne Imaging Radar-c/X-band Synthetic Aperture Radar (SIR-C/X-SAR) mission was a cooperative endeavor of the United States, Germany, and Italy. The SIR-C/X-SAR scientific research program was a large international cooperative program of radar for Earth observation in which 13 countries participated, including China. SIR-C/X-SAR, with the ability to acquire polarimetric SAR and integer...

There have been rigorous research and dev elopment of unmanned aerial vehicles in the field of search and rescue (SAR) operation recently. UAVs reduce unnecessary human risks while assisting rescue efforts through aerial imagery, topographic mapping and emergency delivery. The app lication of UAVs in offshore and nearshore marine SAR missions is discussed in this paper. Projects that integrate ...

Great numerical complexity is a characteristic of synthetic aperture radar (SAR) image synthesis algorithms that poses a particularly serious problem for realtime application. Advances in the operating speed and density of the field programmable gate arrays (FPGA) have allowed many high-end signal processing applications to be solved in commercially available hardware. A realtime SAR image proc...

How can the concrete meaning of the ambiguous and theoretical concept of sustainable development (SD) be defined and implemented, without losing sight of its fundamental principles? This study introduces a theoretical framework that supports studies of SD implementation in the context of strategic disaster risk management, by defining what SD implies with regard to planning procedures. The fram...

Ship detection and classification with space-borne SAR has many potential applications within the maritime surveillance, fishery activity management, monitoring ship traffic, and military security. While ship detection techniques with SAR imagery are well established, ship classification is still an open issue. One of the main reasons may be ascribed to the difficulties on acquiring the require...

Within the paper the automatic matching of existing GIS data to airborne SAR scenes for georeferencing is discussed. For this purpose simulated SAR images are generated based on the available GIS objects using a SAR simulator. These simulated scenes are matched against the captured SAR image in order to detect the given GIS objects in the SAR scene. The feasibility of the approach is demonstrat...
