摘　　要：为验证多根车载天线之间不因集成在同一城轨车辆上而出现共址干扰现象,提出一种适合城市轨道交通车辆车载天线电磁兼容性的评估方法。通过分析天线互扰形成要素,以及在装车前后电磁环境的变化情况,筛选出可能发生共址干扰的天线组合,再通过实测被选出天线之间的隔离度来补充评估数据,最后通过计算收发天线能量匹配情况评估天线之间的电磁兼容性。In order to verify that collocation interference between several vehicle-carrying antennae will not take place due to their integration on the same urban rail vehicle,an estimation method applicable to EMC of vehicle-carrying antenna on urban rail traffic vehicles is put forward.Via analysis of factors of forming mutual interference of antennae as well as the change of electromagnetic environment before and after loading on vehicle,the antenna groups that may have collocation interference are screened out,and then the estimation data are supplemented through actual measurement of isolation between the selected antennae,in the end,the EMC between antennae is estimated through calculating the energy matching of the transceiver antenna.
