摘要
采用频域分析方法分析机动平台的电磁频谱特性,针对发射机系统产生的谐波对Glonass导航设备所造成的电磁干扰,利用电磁仿真设计软件EMC Studio进行仿真计算,从而获得最大干扰路径和干扰信号幅度,并给出具体的改进设计方法和处理措施,实现系统兼容工作。
The electromagnetic frequency spectrum characteristics of mobile platform are analyzed by using frequency domain.The electromagnetic interference of Glonass navigation equipment by the harmonic components coming from transmitter system is detected.The maximal interfering route and relative amplitude of interference signals are determined by electromagnetic simulation software EMC studio.The solution measures and improved design are presented to realize compatible work.
