摘要
对通信设备受扰等级进行了精细划分,建立了通信设备定性受扰分析评估模型。通过建立电磁干扰余量与设备受扰工作性能指标间的映射关系,从语音清晰度指数、数据通信误码率和通信容量三个指标给出了通信设备受扰程度定量评估方法。通过应用实例进行了数值仿真计算,结果表明:该受扰性能评估方法实用性强,易于工程实现,给通信装备效能评估提供了依据,为雷达、导航等用频设备的电磁干扰效应评估技术研究提供了有益的参考。
The interference grades are refinedly defined to establish the electromagnetic interference evaluation model.According to the relationship between electromagnetic interference margin and the operational performance parameters for communication device,including articulation index,error rate,and communication capacity,the techniques are presented to translate electromagnetic interference prediction results into operational performance evaluation.The presented techniques are illustrated by several examples,and the results show that the techniques of performance evaluation for communication device have a good utility and are easy to realize,which are meaningful for the study of electromagnetic interference effect evaluation of radar,navigation,and other services.
