Satellite coherent Doppler wind lidar performance simulation based on CALIOP measurements

摘要

A computer simulation tool using MATLAB has been developed based on the coherent Doppler lidar theory. The measurement performance of a satellite coherent Doppler wind lidar is computer simulated using the CALIOP measurements instead of aerosol model. Frehlich's two-parameter model is used to characterize the performance of the velocity estimates. The accuracy of radial wind velocity good estimates and the fraction of good estimates, depending on backscattered signals from aerosols, generally decrease with altitude. The simulation results demonstrated that a global wind profiling of the lower troposphere from space is feasible using a coherent Doppler wind lidar with achievable system design, appropriate performance setting and parameter selection.
