Abstract :
Power level and phase difference of two linearly polarized, wanted and unwanted, 30-GHz signals transmitted by ATS-6 during its European campaign are measured. The analysis of a cross-polar discrimination (XPD) event reveals the possibility of improving XPD by a simple rotation of the feed systmn. The procedure applied could be self-adaptive where the phase difference between both components could serve as the variable criterion.
