星间相干激光通信中反射镜面形畸变状态下通信性能的研究
Effect of the surface shape distortion of mirror on satellite based on coherent laser communication
摘要
单个激光波长受卫星相干光通信系统中反射镜的影响, 其波前将会发生不可预期的变化。研究了波前在单个反射镜面形畸变下的变化, 并分析了它对卫星相干光通信效率的影响。仿真结果表明, 畸变位置处的峰谷值是影响激光波前的主要因数, 而畸变的大小对链路性能的影响却有限。
Abstract
The single laser wave front aberration which is caused by reflection mirror in the coherent laser communication is studied. The wave front mismatch caused by the signal to local oscillator field coherence in coherent laser communication systems is analyzed. The result of simulation shows that the peak to valley (PV) is the main factor of the performance decline of laser communication system. But the size of reflection mirror aberration influences the system little.
