| 摘 要： | 文中提出了改进的双通道Fabry-Perot(F-P)干涉仪大气风场和温度测量激光雷达系统。该系统采用偏振隔离技术，提高了Rayleigh散射信号光强的利用率，从而提高了系统的测量精度。通过对系统的数值模拟计算，结果表明：风速和温度的测量精度在30km高度分别达到1.5m/s和1.8K，与过去的系统相比测量误差分别降低了近40%和30%。

| Abstract: | An improved lidar system with a double edge interferometer for wind and temperature of the atmosphere is proposed in the paper.The optical isolation has been used to improve the efficient of the system,and thus the measurement accuracy.The numerical simulation of the system has resulted that the accuracies for wind and temperature are within 1.5m/s and 1.8K at the height of 30km,i.e.the errors are decreased compared to the previous system by 40% and 30% respectively. |
