摘要:

深空探测具有时延长、运动速度大以及信号强度低的技术难点。在对上述技术难点进行分析的基础上，提出了对深空动态模拟的解决办法：通过利用闭环双口RAM来解决模拟时延较长的问题；改变读出双口RAM数据的速率来模拟卫星的运动速度；控制数控衰减器来模拟深空的信号强度。实际的工程应用证明上述实现方法有效可行。

Abstract:

The deep space exploration has the characteristics of long time delay, high sate llite′s velocity and the weak signal. Based on analysis of the above technique difficulties, the solution is proposed:the close loop dual-port RAM is used to s olve the long time delay simulation,the reading data speed from dual-port RAM is changed to simulate the satellite′s velocity，and through controlling the digi t al attenuator the deep space′s signal intensity is simulated.Engineering applic ations have proved the feasibility of the solution.
