The AWIATOR airborne LIDAR turbulence sensor
Aerospace Science and Technology, 2007The development and first flight tests are described of a short pulse direct measuring UV LIDAR for the measurement of gusts, turbulence and potentially wake vortices. The results of these stage 1 tests confirm that relative wind velocities can be measured with a standard deviation of below 10 m/s even at high altitudes with no appreciable aerosol ...

Phenomenological, Measurement Based LiDAR Sensor Model
2021The advancing automation within the mobility sector poses new challenges. The open parameter space of potential traffic scenarios turns out to be difficult in the development and certification of advanced driver assistance systems. Scenario based, simulative validation of driving functions appears to be a promising solution.

Points Registration for Roadside LiDAR Sensors
Transportation Research Record: Journal of the Transportation Research Board, 2019Roadside LiDAR deployment provides a solution to obtain the real-time high-resolution micro traffic data of unconnected road users for the connected-vehicle road network. Single roadside LiDAR sensor has a lot of limitations considering the scant coverage and the difficulty of handling object occlusion issue.

The AWIATOR airborne LIDAR turbulence sensor
CLEO/Europe. 2005 Conference on Lasers and Electro-Optics Europe, 2005., 2006Within the European Commission's 6/sup th/ framework program "AWIATOR", an airborne turbulence sensor system was developed using a short-pulse, UV direct-detection LIDAR, which will be presented here. The system is designed to feed back turbulence data into the aircraft flight control system in order to directly counteract the turbulence influence on ...

Die Einsatzgebiete reichen mittlerweile von der Kartografie über die Forstwirtschaft und dem Einsatz im Militär bis hin zu ...openaire +1 more source
Doppler lidar atmospheric wind sensor: reevaluation of a 355-nm incoherent Doppler lidar
Applied Optics, 1990We reevaluate the performance of an incoherent Doppler lidar system operating at 354.7 nm, based on recent but well-proven Nd:YAG laser technology and currently available optical sensors. For measurements in the lower troposphere, up to ~5 km altitude, and also in the Junge-layer of the lower stratosphere, a wind component accuracy of +/- 2 m/s and a ...
