Space-borne coherent Doppler lidar

摘要

Global wind profiling with a space-borne Doppler lidar is expected to bring big progress in the studies on global climate modeling and accurate numerical weather prediction. This research program aims at a demonstration of the coherent Doppler lidar technology in space. CRL has been conducting feasibility study on the coherent Doppler lidar aiming at demonstration onboard the Japanese Experiment module of the International Space Station. We are in parallel developing an airborne coherent Doppler lidar system to measure wind profile under a jet plane for simulation of the Doppler lidar measurement in space. This system is also operated in the ground to develop algorithm of the wind measurements.
