摘　　要：信道作为指令与数据接收站(CDAS)与FY-2气象卫星进行数据交换的最前端分系统,其所受干扰直接影响地面应用系统对数据的接收与处理。文章基于CDAS信道分系统设计原理及设备组成,针对FY-2F星在轨测试期间出现的信道干扰提出了有效的干扰源排查流程及定位措施;最后,结合周边环境对干扰原因进行分析论证,证实了干扰源定位的准确性;并对现有系统进行优化处理,干扰排除效果较好。As the foremost system exchanging data of Command Data Acquisition System （CDAS） and FY-2 meteoro- logical satellite, the channel will directly effect data receiving and processing of the system if it is disturbed. Based on design principle and equipment composition of channel sub-system in the CDAS, this paper puts forward effective investigation process and locating measures in connection with the channel interference occurring during the in-orbit testing of the FY-2F. It also analyzes and arguments the cause of the interference combining with the surrounding, which verifies the correct location of interferences. This paper also optimizes the current system in the end, resulting in rational effect of the measure.
