摘要
从光功率的角度,分析了卫星间长距离和出射光束发散角产生的空间传输损耗,当传输速率增加、误码率上升时,接收机灵敏度下降;讨论了不同卫星数目时传输损耗与激光束发散角的关系,在考虑其他光功率开销后,得出了发射光功率,发散角和接收灵敏度相互制约关系。
This paper introduces the properties of optical power budget in TDRSS抯 laser communication links. For various condition of different transmission distance and divergence angle, the attenuation in space is studied in detail. According to the requirement of TDRS system, the transmitting power is also specified in the paper.
