系统地研究了一种基于后向散射信号的光学闪烁机理的多激光光束风场测量(MLBM)系统及其性质。在实时检测过程中,使用光学互相关方法对信号进行分析得出了固定距离200m处的近场风速及风向信息;同时,测量并计算了在不同时刻和不同系统摆放情况时的风速。实验结果表明,测量得到的风速与参照风速之间的相对误差小于5%。 A multi-laser beam wind field measurement (MLBM) system and its properties based on the optical scintillation mechanism of backscattering signal are systematically studied. In the process of real-time detection, the signal was analyzed by optical cross-correlation method to get the near-field wind speed and wind direction information at a fixed distance of 200m. At the same time, the wind speed was measured and calculated at different times and different systems. Experimental results show that the relative error between the measured wind speed and the reference wind speed is less than 5%.
