Transhorizon 2 GHz angle-of-arrival measurements and analysis

摘要

Received signal level and angle-of-arrival measurements are being recorded on a 93 km, 2 GHz experimental transhorizon link on an overland path in East Anglia, UK. Significant periods of signal enhancement have been observed, associated with stable atmospheric conditions. The link and experimental system is described and preliminary results are analysed primarily with reference to a reflecting-layer propagation model.
