摘要
以星地通信链路为例阐述了利用STK/Matlab接口与Matlab程序进行动态链路数据交互的联合仿真方法,通过大气吸收模型和雨衰模型等逼真星地信道的衰落情况,适当选择链路的约束参数,从而计算确定满足链路约束的卫星天线增益等关键参数的设计门限,可用于指导星上通信系统的设计,解决了传统链路计算只能用于通信系统设计结果验证的局限,为卫星通信系统设计提供了一个高效的辅助手段。
In order to analyze satellite communication link budgets dynamically, an accurate calculation method based on STK （Satellite Tool Kit）/Matlab interface is presented.By this method,atmospheric absorption model and rain attenuation model integrated in STK are considered through data exchange between STK and Matlab program,then key parameters involved in link design,such as minimum satellite antenna gain,are determined to meet the threshold constraint at the first try. It also provides an efficient means of satellite communication system design.
