摘　　要：讨论了日像仪的干扰容限,列出了干扰源分布,估算出干扰测试仪灵敏度。计算了同步卫星干扰及干扰时间预测,也分析了中低轨道卫星干扰问题。对移动通信基站产生的干扰作了传播分析、计算,对脉冲雷达干扰作了谱分析及保守计算。The electromagnetic interference tolerance is discussed in this paper, the radio spectrum assignment and the sensitivity of interference measurement equipment are described. Interference to CSRH and forecast from synchronous orbit satellite, and interference due to low and middle orbit satellite are analysed. Transmission formula of interference from mobile base and conservative estimation from pulse radar are presented.
