Simple signal-to-noise parameterization scheme to assess lidar performance and its applications

摘要

A general methodology for rating both performance and potential of lidar systems used for detection of atmospheric trace constituents is developed. This is carried out via a generalized figure of merit, V, for lidar quality by consideration of both lidar system parameters and atmospheric operating conditions on signal-to-noise-ratio. Based on V and atmospheric parameters, computer simulations are carried out and simple design procedures are outlined to determine achievable lidar performance and ensure the best monitoring efficiency for a given set of initial requirements.
