Compatibility study between CDR and aeronautical radio navigation service ILS/VOR

摘要

China's digital audio broadcasting FM-CDR (Convergent Digital Radio) uses the 87-108MHz frequency band, which is adjacent to the frequency range of the aeronautical radio navigation service, so research on the compatibility between digital sound-broadcasting service and aeronautical radio navigation is very important to promote the development and popularization of FM-CDR. This paper introduces the research situation and related test results of compatibility between FM-CDR and ILS (Instrument Landing System) /VOR (VHF omnidirectional radio range).
