摘　　要：针对浦东机场现有的三种航向天线系统在实际运行中的差别,通过天线信号分配关系,结合附件10^([5])规定的技术指标进行差异性分析。通过理论计算并采用MATLAB建模以实现对天线的排布特点、信号合成、抗干扰能力等方面的量化分析。根据实际飞行校验结果,采用航向天线的专业Atoll软件进行计算、对比和验证。根据比较结果对天线的可靠性和设计合理性予以评估,为天线选型提供参考依据。There are three types of localizer antenna systems in Pudong New Area Airport, the function of them is evaluated and studied by signal distribution and annex 10^[5]. The difference of quality is compared through mode of antenna array, anti interference ability and reliability. Data analysis by MATLAB modeling as well as theoretical calculation support the qualitative result to evaluate the coverage, difference of degree of modulation （DDM）, beam bend potential （BBP） of three types. The results coincide with flight checking data. Meanwhile they are consistent with the model established by Atoll, therefore the reference evidence of antenna system selection is provided for.
