摘　　要：本文对特种激光外差通信系统接收中频信号相位受大气湍流随机起伏进行了实验测试。实验结果表明:该系统有助于克服大气湍流对接受中频信号相位的随机起伏,由大气湍流带来的随机相位噪声可以不予考虑。The phase fluctuations of receiving IF signal of special type laser heterodyne communication system are measured. The experimental results show that the phase fluctuations caused by atmosphere turbulence of the received IF signals of this system are negligible. No noise effect is added to the system due to phase fluctuations.
