摘要
整车平台上电子设备密集,通过电磁仿真得出射频天线系统间的干扰矩阵表,分析了系统间的干扰源、电磁干扰裕度,并利用空间隔离、添加滤波器、调整接收频谱等优化措施,抑制各射频天线系统间的干扰,降低车载射频设备的电磁兼容风险。
The electronic equipment on the vehicle platform is dense,and the interference matrix between RF antenna system is obtained through electromagnetic simulation.The interference sources and electromagnetic interference margin between system are analyzed.Optimization measures such as space isolation,adding filters,adjusting the receiving spectrum are used to suppress the interference between RF antenna system and reduce the EMC risk of vehicle borne RF equipment.
