摘　　要：基于航空无线电技术委员会(Radio Technical Committee for Aeronautics,RTCA)等的相关技术标准,结合卫星通信链路预算理论,给出全球导航卫星系统(Global Navigation Satellite System,GNSS)机载天线增益适航性分析的理论方法,并对北斗卫星导航系统(Beidou Navigation Satellite System,BDS)机载天线增益进行适航性分析计算。以BDS机载天线增益适航性分析结果为设计指标进行BDS B1I频段机载无源天线的验证设计与仿真。BDS机载无源天线仿真结果满足设计指标,并具有良好的低仰角增益与圆极化性能。证明了所给GNSS机载天线增益适航性分析方法的可行性与BDS机载天线增益适航性分析结果的合理性。Based on the relevant technical standards of Radio Technical Committee for Aeronautics(RTCA)and others,the theoretical method for airborne antenna gain airworthiness analysis of Global Navigation Satellite System(GNSS)is given in combination with satellite communication link budget theory,and airworthiness analysis calculation of airborne antenna gain of Beidou Satellite Navigation System(BDS)is carried out.The results of BDS airborne antenna gain airworthiness analysis are used as the design index for the verification design and simulation of BDS B1I band airborne passive antenna.The simulation results of BDS airborne passive antenna meet the design index and have good low elevation gain and circular polarization performance.The feasibility of the given GNSS airborne antenna gain airworthiness analysis method and the reasonableness of the BDS airborne antenna gain airworthiness analysis results are demonstrated.
