The knowledge of ocean characteristics and a better understanding of sea physics are of unquestionable interest, not only on scientific grounds, but because of their connection to global meteorology and the impact of this on human lives. Research of such complex matters demands extensive data collection, since the phenomena object of study might take place over very wide spatial and time ranges. The development of remote sensing techniques alongside space technology has made possible the availability of data on a global scale and improvements in computing have had strong repercussions on the processing of the acquired observations, fostering the growth of these disciplines.

The creation of the Global Positioning System entailed the deployment of a net of satellites constantly orbiting around the Earth and transmitting wellcharacterized signals that were first pointed out as sources of opportunity for remote sensing measurements in 1993 ([32]): the signals reflected off the Earth s surface would carry information about the position and constitution of the reflecting area. The concept was named PARIS (PAssive Reflectometry and Interferometry System). It was an alternative purpose of the GPS other than navigation or positioning bringing about an unprecedented source of data. In particular, oceans and seas constitute reasonably good reflecting surfaces at the wavelengths of these signals because of the dielectric properties of sea water. A new way was open for ocean research.

Since then, several laboratories and institutions have been working on the field: the Jet Propulsion Laboratory, the Goddard Space Flight Laboratory and the Langley Research Center from NASA and the Environmental Technology Laboratory (NOAA) in the USA, and the European Space Research and Technology Centre (ESTEC) from ESA in the Netherlands. The works within this discipline at IEEC started in 1997.

Any scientific venture goes through four fundamental steps, the four essential elements of the scientific method: characterization of the problem (observation and quantification), formulation of hypotheses, prediction (logical deduction from the hypotheses) and experiment. All these steps require time, effort and multitude of tasks to accomplish, and their execution leads to a further stage where the procedure starts again. The present work has to be regarded as a small contribution within the chain of activities meant to explore the way to exploit the possibilities GPS reflections offer. The goal of the project has been to ascertain the validity of a physical model (prediction / experiment) and to implement software routines that prepare the data output by a receiver of recent completion developed at IEEC, the GOLD-RT receiver, to be processed using this or an enhanced physical model. Appendix B recapitulates the main features of the GOLD-RT receiver.
