Open full text 1 citations

Abstract

The airborne coherent Doppler lidar could provide the wind velocity relative to the motion of the lidar.The retrieval algorithms are complex corresponding to Ground-based lidar, due to the Doppler shift caused by mobile platform.This article gives a thorough analysis of the wind retrieval algorithms for the wind products of airborne Doppler lidar, include the correction for the lidar velocity measurement.Most of data correction method is introduced in this paper, including the data correction of attitude, velocity, and ground return and so on.Those methods will be necessary for the accuracy improvement of wind detection of airborne Doppler lidar.
