摘　　要：系统电磁兼容(EMC)设计中,无线设备间互调干扰是非常严重的一个问题。本文首先建立了无线设备间互调干扰量的分析模型,并采用矩量法结合微波网络的方法求出互调干扰模型中最重要的参数天线间耦合度,然后把发射及接收设备的给定数据代入干扰模型算出发射机和接收机间互调干扰的量级。经过仿真数据与实测数据的对比,证明该方法理论正确,计算精度较高,文章最后给出了仿真实例。Intermodulation interference is a most serious problem in the electromagnetic compatibility （EMC） design. In this paper,a model of intermodulation interference is established first and on the base of this we bring forward a idea which combining the iOi and microwave network theory to calculate the most important parameter in interference model： coupling,and then we can get the level of intermodulation interference by displacing the rated values of equipment parameters into the interference model, the method is validated by comparisons between theory and experiment data. In the end we oive a example of the emulation process.
