One of the main goals of the future SWOT (Surface Water Ocean Topography) space mission is global monitoring of the continental water surfaces in the world. This requires automatic river network recognition in order to characterize the temporal evolution. It is expected that detection of rivers having widths greater than 50-100m will be possible.

In this paper, High Frequency Surface Wave (HFSW) Radars are considered for target detection at long range. The received signals of the HFSW Radar are strongly polluted by different noises. To detect targets in these noisy data, a method based on Morphological Component Analysis (MCA) initially proposed by Starck et al. [1, 2] is investigated. Simulated(More)
We simulate the Doppler spectra that can be obtained under experimental conditions from bistatic highfrequency oceanic radar. For this, we combine the bistatic secondorder theory with the characteristics of the full radar system, such as antenna patterns, range attenuation, and postprocessing of the received signal. Because of the sharp variation of the(More)
