Using Reflected GNSS Signals to Estimate Surface Features Over Wide Ocean Areas

The complete and continuous illumination of the oceans with signals from Global Navigation Satellite Systems (GNSS) has been used to investigate the capability of a Low Earth Orbit (LEO) mission scenario to measure surface characteristics over wide ocean areas. The concept is based on receiving and processing both the direct and ocean reflected signals from a certain number of satellites. A software simulator has been developed for an aircraft scenario. The basic magnitudes for a possible array antenna configuration in the case of the LEO satellite scenario have been derived. Finally, a validation of the theoretical results with data collected during field measurements over sea water from a bridge is presented.
