Maritime Domain Awareness–a possible major component

Onera, a French Aerospace research center, claims to have developed a “surface wave radar” that follows the curvature of the Earth and provides coverage out to at least 400 kilometers (about 220 nautical miles). It is claimed to detect air as well as surface targets, with ranges limited only by transmitter power. The system was tested in June 2010 at Biscarosse in Southwestern France. They tell their story here.
