机动式指挥系统无线设备间谐波干扰量分析

机动式指挥系统电磁兼容设计中,谐波干扰是最为严重且较难抑制的一个问题。本文首先探讨了无线设备间耦合干扰现象,建立了设备间耦合干扰的分析模型,并采用矩量法结合微波网络的方法求出模型中重要参数天线间耦合度,然后采用标准测试的方法求得设备间谐波干扰量。经过仿真数据与实测数据的对比,证实该方法理论正确,计算精度较高,对机动式指挥系统电磁兼容设计有较强的指导意义。

Analysis of Magnitude of Harmonic Interference between Wireless Stations in Mobile Communication System

In the design of the EMC of mobile communication system,harmonic interference is the most serious problem.The phenomena of coupling interference between wireless stations in mobile communication system is presented by authors.Setting up the analysis model of coupling interference,this paper uses the moment method combined with theory of microwave network to find out the mutual coupling between two antennas which is an important parameter.Then using the method of standard measuration to calculate the magnitude of harmonic interference between equipments.Finally,through the comparision between emulational date and practice date,confirmed that the theories are correct method and have the high accuracy.
