CW Lidar for Wind Sensing featuring numerical range scanning and strong inherent suppression of disturbing reflections

摘要

A low-coherence continuous wave Doppler Lidar using a synthetic broadband source has been suggested recently. The main advantages are electronically adjustable spatial resolution, strong discrimination between signal contributions from different locations and the enabling of after-measurement numerical range scanning. In this paper an advanced concept is presented with an efficient suppression of unavoidable perturbations from inside the measurement setup.
