摘要
鉴于当前卫星通信链路计算过程中,链路影响因素考虑不精细,研究了在链路传输过程中可能存在的各种损耗及干扰,及发射天线和接收天线特性,提出一种精细的链路计算模型,并通过实例计算验证该计算模型的可行性。该模型可用于指导通信人员对系统设备和链路参数的选择,及对链路性能的预测。对卫星通信组织运用具有指导意义。
In view of the inaccuracy of the link influencing factors in the current link calculation process of satellite communi cation,various possible losses and interference in the link transmission process,as well as the characteristics of transmitting and re ceiving antennas are studied.The model can be used to guide communicators to select system equipment and link parameters and predict link performance.It has guiding significance to satellite communication organization and application.
