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)
In this paper we analyse the GPS signals reflected by the surface of the ocean to retrieve information about the sea surface roughness, expressed in statistical terms by means of the sea surface Mean Square Slopes (MSS). Particularly, we perform Delay-Doppler mapping of real scattered GPS signals from the Surrey Satellite Technolody Ltd UK-DMC mission , and(More)
1. ABSTRACT GNSS-Reflectometry is a revolutionary approach to Earth Observation and is recently undergoing rapid advances, especially because the signals of opportunity scattered worldwide from the ocean surface can be used to investigate many important geo-physical properties in a near-real time. Global sampling and high temporal resolution of GNSS-R(More)
