Millimetre Wave Propagation Over the Sea

摘要

Three measurement campaigns concerning the propagation of millimetre waves abovethe sea have taken place on the French Atlantic coast near the town of Lorient (Brittany). The length of the propagation path was 9.7 km. Due to the low position of the antennas also the sea surface was illuminated and part of the transmitted energy was reflected by it. From the analysed propagation and environmental data, mainly at 36 and 94 GHz, it appears that the following phenomena have a major influence on propagation: reflection at the sea surface, attenuation due to rain and non-standard atmospheric condition.
