The Canadian Olympus propagation experiment
Abstract
The planning of commercial and military satellite communications systems using the upper SHF and lower EHF bands has resulted in a need for more propagation data and models for these bands. This is especially true for VSAT systems using small attenuation margins for which accurate data are particularly scarce and existing models inaccurate. The Canadian Olympus propagation experiment, designed to obtain such data, is described. The experiment includes simultaneous attenuation and depolarization measurements using the 12-, 20-, and 30-GHz Olympus satellite beacons, radiometric measurements of attenuation at 14, 20, and 30 GHz, and polarimetric radar measurements at 9.6 GHz. One novel feature of the experiment is the attempt to use the radar data to help separate the statistics of melting layer attenuation from beacon-measured total attenuation.
