摘　　要：调频频段数字音频广播FM-CDR与航空无线电导航业务的兼容性研究对于推动地面数字广播在我国的大规模推广至关重要。在此分析不同频率下的数字音频广播对航空无线电导航信号可能产生的干扰情况,并在综合国内外对FM,DRM,HDRadio等音频广播技术相关兼容性研究课题的基础上,提出可以用于实际开展的兼容性测试方案。通过选取设备、搭建平台、初步测试、数据收集以及统计分析,验证了该测试方案的合理性,并且得到了干扰信号与欲收信号同频条件下FM-CDR与ILS,VOR业务之间的兼容性情况。It is very important for promotion of the large?scale popularization of digital terrestrial broadcasting in China toresearch the compatibility between the FM?CDR and aeronautical radio navigation services.The interference possibly generatedby digital audio broadcasting at different frequencies on aeronautical radio navigation signal is analyzed.On the basis of the rele?vant compatibility research subjects of FM,DRM,HDRadio and other audio broadcasting technologies,a compatibility testscheme is presented,which can be applied to the actual mission.The rationality of the test scheme was verified by means of de?vice selection,platform construction,preliminary test,data collection and statistical analysis.The compatibility between the FM?CDR and aeronautical radio navigation systems(ILS and VOR)at a same frequency of the receiving signal and interference sig?nal was obtained.
