基于大气分层的激光测风雷达回波模型

Echo Signal Model of Coherent Doppler Wind Lidar Based on Slicing of Atmosphere Theory

从相干激光测风雷达原理入手,论述了激光雷达回波特性和多普勒效应在测风雷达中的应用。基于大气分层模型,考虑到激光束的传播及其与大气之间的相互作用,建立了激光测风雷达回波模型,模拟回波信号在大气中的传输过程,为激光测风雷达回波信号的模拟提供了理论基础。

The wind detection principle of lidar and the basic principle of coherent detection are introduced and the echo signal characteristics of wind lidar were analyzed. Based on the theory of slicing of the atmosphere,we propose an echo signal model of coherent Doppler wind lidar,considering the interaction between laser beam and atmosphere. The transmission process of echo signal in the atmosphere can be simulated. This provides a theoretical basis for the echo signal of wind lidar.
