Moving Object Detection and Tracking with Doppler LiDAR
Remote Sensing, 2019 In this paper, we present a model-free detection-based tracking approach for detecting and tracking moving objects in street scenes from point clouds obtained via a Doppler LiDAR that can not only collect spatial information (e.g., point clouds) but also

Monitoring Dust Events Using Doppler Lidar and Ceilometer in Iceland
Atmosphere, 2020 Ground-based lidars and ceilometers are widely used for dust and volcanic ash observation around the world. This is particularly interesting in Iceland where high-altitude dust events occur frequently during strong wind conditions and volcanic eruptions.
