Uncertainty in Calibrating Flood Propagation Models with Flood Boundaries Derived from Synthetic Aperture Radar Imagery
An instantaneous synthetic aperture radar (SAR) derived flood extent map helps retrieving the distributed conveyance parameters in one-dimensional flood routing models. These models are generally calibrated based on the sole use of ground data. This research aims to use earth observation (EO) data in order to establish a significant parameter retrieval strategy, providing an alternative model c...

متن کاملThe Object Detection Efficiency in Synthetic Aperture Radar Systems
The main purpose of this paper is to develop the method of characteristic functions for calculating the detection characteristics in the case of the object surrounded by rough surfaces. This method is to be implemented in synthetic aperture radar (SAR) systems using optimal resolution algorithms. By applying the specified technique, the expressions have been obtained for the false alarm and cor...
متن کاملWind Energy Mapping Using Synthetic Aperture Radar
Wind energy off-shore is gaining much interest due to the high wind power potentials. The need is to map wind climatology and regional wind patterns in coastal regions. In the WEMSAR (Wind Energy Mapping using Synthetic Aperture Radar) project three European sites will be covered near Norway, Denmark and Italy. Data to be used are from the ERS-2 C-band scatterometer with a 50 km resolution, fro...
