摘　　要：在空间通信数字仿真中接入通信链路和通信信号等实物,使仿真具有更强的实时性,仿真结果也具有更好的实际应用价值。本文分析比较了空间通信链路数学仿真和半实物仿真的优缺点,提出了空间通信链路半实物仿真平台的原理框图,设计出开路和闭路2种空间通信链路半实物仿真方法,重点阐述了空间微波链路传输特性模拟、空间微波链路通信质量评估的实现。通过对某星间链路的通信与对抗实例分析,该方法是可行的。A solution of mathematics simulation for space communication links connecting with hardware can be carried out to support real-time simulation. This paper analyzes the merits and shortcomings between mathematics simulation of space communication chain and semi-physical simulation, and designs both circuit-opened and circuit-closed space communication chain methods for the semi-physical simulation. The paper takes the characteristic simulation of space microwave chain transmission and the evaluation of communication quality of space microwave chain as key researches. The results of simulation on satellite communication links show that the performance of platform is effective and practical.
