摘　　要：舰载电子设备处于有限空间内,电磁信号密集,相互间干扰日益严重。通过引入电磁干扰余量建立预测方程,结合干扰三要素通用预测模型,分析了电磁干扰综合预测原理方法,并对电子设备四种干扰余量进行仿真计算,最后根据结果分析电磁干扰的可能原因,并提出了干扰抑制方法。Shipborne electronic equipments are in the limited roomage, the electromagnetic signals are so dense that electromagnetic interference（EMI） among electronic equipments becomes more and more serious. By leading the electromagnetic interference margin, this paper sets up the prediction equation,and analyzes the principle and method of integrative prediction to the EMI combining with the general prediction model of three interference elements,and implements simulative calculation to four interference margins of the electronic equipments, finally analyzes the likely reasons that cause the electromagnetic interference,and presents the method to suppress the interference.
