摘　　要：首先对造成气象卫星云图接收质量下降的影响因素进行分类分析,从来源、途径、终端3个方面入手研究采取相应措施避免或者减少这些因素带来的损失。链路计算作为合理规划设计系统的关键点之一,以其预算结果为指导依据,结合接收设备性能参数和实测数据,制定排查方案以应对试验中出现的各种问题。给出无线对接试验中一排查实例,表明该方法可作为故障排查的一般方法,对在轨测试和业务运行都具有实际指导意义。把握接收前端3种关键设备的性能参数核查、接口电平计算及合理分配的工作方法,对进一步提高卫星云图接收质量提供了重要依据。This paper classifies influencing factors which causing the decline of satellite cloud image receiving quality,and takes measure to reduce the loss.It develops solution to problems in the experiment,based on the performance parameters,measured data and the link calculation results,which is one of the key points of the system design.A measuring example is given,and the method feasibility is proved,which has practical guiding significance for on orbit test and job running.At the same time,this solution can also be used as a general method of trouble shooting.The method which grasps the performance parameters of three key receiving front end equipment,calculation and reasonable distribution of interface level,provide important basis for reception quality of satellite cloud image.
