超短波通信装备复杂电磁环境适应能力评估

Evaluation on Fuzzy Electromagnetic Environment Adaptation Ability of Ultra-shortwave Communication Equipments

以超短波通信装备的电磁环境适应能力为研究对象,基于实体设备的六种不同调制样式通信信号的抗干扰性能测试数据,建立同频干扰、邻道干扰、中频干扰、镜频干扰、互调干扰等电磁环境要素的评估指标集,对实测数据进行量化,采用层次分析法进行评估,比较不同调制样式通信信号的复杂电磁环境适应能力。

This article takes the fuzzy electromagnetic environment adaptation ability of ultra-shortwave com- munication equipments for research object. Based on the anti-jamming performance testing data, which is gained from six different modulation signals of equipments, the evaluation index set from electromagnetic environment factors is constituted. The factors are list as follows： co-channel interference, adjacent channel interference, intermediate frequency interference, image frequency interference, inter-modulation interference, and so on. The actual data is quantized, and then evaluated adopting analytic hierarchy process so as to comparing electromagnetic environment adaptation ability of varies modulation modes.
