摘　　要：利用风云三号气象卫星接收信号的频谱图,分析卫星接收设备的运行情况,查找信号干扰的来源,排除接收设备的故障,解决接收云图中存在的问题,从而提高云图接收质量。Based on the signal frequency spectrum of FY-3 meteorological satellite, the operation of satellite receiving equipment is analyzed. This paper finds out the source of signal interference and removes the equipment breakdowns. The problems exist in cloud map receiving are solved and the cloud quality is improved.
