摘要
介绍了基于双Fabry!Perot标准具的测风激光雷达的工作原理,分析了大气分子散射对风速测量的影响,并给出了相应的数据处理方法。模拟并分析了两种不同迭代初值在1～3次迭代时产生的系统测量误差,给出了1km和5km处风速的测量误差。利用自行研制的一台多普勒测风激光雷达对合肥地区对流层风场进行测量,并用两种方法处理了实验数据。结果表明,改进的数据处理方法是切实可行的。
The measured principle of Doppler wind lidar based on a dual Fabry-Perot etalon is described. The effect of atmospheric molecular scattering on the measurement of wind speed are analyzed, and the correspending data processing methods are shown. Measured error with 1-3 times iterative of two difference iterative values are simulated and analyzed. The measurement errors of wind speed at 1 km and 5 krn altitude are given. The Doppler wind lidar developed by ourselves is used to measure the troposphere wind field in Hefei and the experimental datum are processed using two different methods. Results indicate that the improved method is feasible.
