Slant-path depolarisation measurements at 12 and 14GHz carried out at Martlesham Heath using the OTS satellite
Abstract
Slant-path depolarization statistics at 14.5GHz and 11.8GHz (circular polarization) and 11.6GHz (linear polarization) for the 29.9-deg elevated path to the Orbital Test Satellite (OTS) are presented for the period July 1978-July 1980. In addition the relationship between depolarization and fading is investigated and the measurements are compared with both a CCIR curve and theoretical data supplied by the University of Essex. The dependence of depolarization on the type of polarization and the frequency is also studied. The results clearly demonstrate the superior cross-polar performance of linear polarization compared to circular polarization.
