CARRADA Dataset: Camera and Automotive Radar with Range-Angle-Doppler Annotations

open access: yes, 2021
High quality perception is essential for autonomous driving (AD) systems. To reach the accuracy and robustness that are required by such systems, several types of sensors must be combined. Currently, mostly cameras and laser scanners (lidar) are deployed

Doppler LIDAR Developments for Aeronautics

open access: yes, 2016
Detecting atmospheric hazards such as wake vortices, turbulences, wind shear or wind gusts would improve flight and airport traffic safety. Moreover, to face the current and future challenges of air traffic growth in terms of environment, safety and costs, one of the major challenges is to increase runway throughput by optimizing the distance ...
