| 摘要: |
| 中继卫星的Ku频段单址通道返回链路采用相同的载波频率。链路通过采用天线的相反的极化、波束指向的不同，来减小链路之间的干扰。但是如果链路非常接近，链路之间的相互干扰还是很突出。本文在不影响仿真精度的条件下，对环境做了简化，用数学的方法分析了链路之间的相互干扰。在简化的模型下，用SPW对链路进行了仿真分析，并将仿真结果与数学分析结果进行了比较。 |

| Abstract: |
| The Ku band single access return link via the tracking and data relay system use the same carrier frequency? The interference between spacecraft is minimized by opposite antenna polarization and by TDRSS antenna beam pointing, but if the links are in close proximity, it is expected that mutual interference will be significant. In this paper, the models of the links are constructed and simulated by SPW, and the results of the simulation are compared with the analytical results. |
