This article focuses on methodologies with recurrent use to code examples that try to couple with the flow of the main steps of the SAR processing. The possibility to be comprehensive was prevented by the wide scenario of variations of the focusing algorithm as well as the spread of applications. The reader should look at this work as a sample of(More)
Synthetic aperture radar processing is a complex task that involves advanced signal processing techniques and intense computational effort. While the first issue has now reached a mature stage, the question of how to produce accurately focused images in real-time, without mainframe facilities, is still under debate. The recent introduction of(More)
Image registration is a process encountered in many science fields wherein two or more images are acquired by different sensors, at different positions or times. In the context of remote sensing, image registration is a key step in change detection algorithms, SAR interferometry and data fusion. Basically, it involves four steps: (a) global registration,(More)
—We present the implementation of a facet-based sim-ulator to investigate the forward scattering of L-band signals from realistic sea surfaces and its application to spaceborne ocean Global Navigation Satellite System (GNSS) Reflectometry. This approach provides a new flexible tool to assess the influence of the ocean surface roughness on scattered GNSS(More)
