| 摘 要： | 空间通信在地 空通信中具有广阔的应用前景。大气湍流引起的相位噪声会严重地影响系统的性能,而自适应光学补偿可使问题得到很好的解决。分析了湍流引起的相位噪声问题,并以Hufnagel湍流模型为例,借助结构函数的概念对这一噪声进行了计算。论证了自适应光学补偿方案。

| Abstract: | Laser communication opens up the vast prospects for ground-space communication. System performance is influenced seriously by the phase disturbance caused by atmospheric turbulence and the problem may be solved by using the adaptive optics compensation. The phase disturbance is analysed. To take the Hufnagel turbulence mode as the example, the disturbance has been calculated by using the structure function concept. The compensation scheme of adaptive optics is demonstrated. |
