摘　　要：2014年12月,国家新闻出版广电总局启动了中央广播电视节目无线数字化覆盖工程,调频频段数字音频广播FMCDR在中国开始了大规模应用。由于调频频段数字音频广播与航空无线电导航业务在无线电频带上相邻,存在相互的干扰,分析与研究相邻频段上的FM-CDR与航空无线电导航业务的兼容性对FM-CDR的规模应用有非常重要的意义。本文提出了开展兼容性研究的方法并开展实验室测试,通过对测试数据的分析归纳,得到了不同频率以及不同模式下的数字音频广播FM-CDR与航空无线电导航业务的兼容性情况,为下一步FM-CDR的工程实施和民用航空导航设施建设提供了参考依据。In December 2014, State Administration of Press, Publication, Radio, Film, and Television of China launched the Cen- tral radio and TV digital wireless coverage project, FM-CDR will carry out large-scale application in China. The digital audio broadcasting is adjacent to the aeronautical navigation service in the radio frequency hands, there exists severe mutual interference hetween them; so research on the compatibility between digital sound-broadcasting service and aeronautical radio navigation is very significant to promote the development and popularization of FM-CDR in Cbina. This paper presented research methods to he used fnr actual testing, and practical test was conducted in the laboratory; thruugh data collecting and statistical analysis, this paper summarized the compatibility conclusion between FM-CDR and ILS/VOR under different frequency or mode, providing reference for next FM-CDR project implementation and civil aviation navigation facilities construction.
