Atmospheric Refractive Turbulence Effect on Diffraction-Limited Infrared Coherent LidarKeywords: Coherent lidar,Atmospheric refractive turbulence,Turbulent structural parameter,Signal-to-noise ratio (SNR),Diffraction-limited Abstract: This paper, based on the Kavaya-Suni format, discusses the signal-to-noise ratio equation of the diffraction-limited coherent CO2 lidar in detail, which is applied to atmospheric turbulence. The cumulative SNR and relative SNR, which are all affected by the nonlinear effects of the diffraction-limited Gaussian beam, atmos-pheric molecule and atmospheric turbulence, are simulated by microcomputer. Six instructions for the optimal design of IR CO2 Coherent Lidar System, are provided.
