| 摘 要： | 介绍了用于风切变测量的激光雷达外差探测系统，阐述了其工作原理，根据CO2雷达系统与Ho：YAG雷达系统相关参数进行信噪比模拟和风速误差对比，模拟结果表明波长为2．1μm的Ho：YAG雷达和波长为10．6μm CO2雷达都适合机载低空风切变探测。通过对比表明Ho：YAG雷达的性能更为优良，误差更小，探测距离更远。

| Abstract: | A lidar heterodyne dection system for wind shear measurement is introduced. The working principle is described as well. The correlated factors of CO2 ladar system and Ho∶YAG radar system are simulated by SNR, and the wind velocity measurement erros are compared. The simulation results show that both the Ho∶YAG radar at 2.1 μm wavelengtn and CO2radar at 10.6 μm are suitable for airborn low altitude wind shear detection. The comparison shows that the Ho∶YAG laser has better performance, less errors, and longer dection range. |
