Abstract

Measurements of attenuation and cross-polarization on slant paths from theCtsandComstarD2 satellites to Blacksburg, VA, have been in progress for three years. The data for 1977 and 1978 have been analyzed to determine the extent of severe ice depolarization on these paths, and a number of events have been identified. The behaviour of the observed cross-polarization at 11.7 and 19 GHz in two events has been compared with current theory for ice depolarization.

Analyse

Des mesures de l’affaiblissement et du découplage de polarisation sur des trajets obliques reliant les satellitesCtsetComstarD2 à Blacksburg en Virginie, ont été réalisées pendant trois ans. Les données obtenues en 1977 et 1978 ont été analysées pour déterminer l’importance de la dépolarisation due à la glace sur ces trajets et un certain nombre de phénomènes ont été identifiés. Le comportement de la transpolarisation due à la glace lors d’observations de la propagation à 11,7 et 19 GHz, a été comparé avec celui prévu généralement dans les modèles théoriques.
