摘　　要：导航台自动选择是区域导航重要组成部分,根据进近阶段VOR/DME和DME/DME区域导航要求设计了VOR/DME无线电导航台自动选择算法,引入了DME组对有效导航距离,同时加入了合理的导航台切换准则。利用在MALAB Simulink下建立的VOR/DME导航台选择及区域导航仿真模型,采用广州白云机场以及北京首都机场的区域导航进近航路进行了仿真实验。实验表明该算法能选择有效的导航台,在及时切换为更好的导航台同时能避免导航台切换过于频繁。The automated station selection is an important part of implementing RNAV. According to the requirement of VOR/DME RNAV and DME/DME RNAV during approach flight phase, an automated VOR/DME station selection algorithm was designed. The effective distance of DME pair and station switching rules were introduced in the algorithm. Based on the information of NAVAID stations and RNAV airways in the terminal area of ZBAA and ZGGG; some simulation experiments were performed using the Matlab/Simulink simulation models of VOR/DME station selection and RNAV procedures. The simulation results show that the algorithm selects acceptable and better stations while avoiding unnecessarily frequent station switching.
