22 December 1997 Airborne Doppler lidar wind measurement: housekeeping data as critical parameters
Author Affiliations +
For the airborne measurement of the wind field, exact data of velocity and orientation of the platform are mandatory. Any small deviation in these parameter will cause a systematic error in the estimation of the wind field. In practice all navigation systems like inertial reference systems (IRS) and also GPS have some errors in their data which may lead to a significant error in the estimated wind field. However a conical scanning Doppler lidar like ADOLAR will also offer some information from the ground return which can be used to select and correct most of the housekeeping data from the other systems. This paper describes briefly the Doppler lidar used for the wind measurements and then extends on the different processing steps necessary to retrieve the 3D wind field with an accuracy better than 1 m/s. The campaign with the airborne Doppler Lidar ADOLAR on board the DLR research aircraft Falcon F20 at November 96 will be used to illustrate this topic. At this campaign three flights were performed at Bavaria, the North sea , and the Baltic Sea. Especially at the first flight in Bavaria approximately one . hour of lidar data with ground return have been obtained. This allows an extended comparison of the different sources of housekeeping data like IRS, GPS, and the Doppler Udar itself.
