A case study of lidar detection ability of elevated duct
We have theoretically studied lidar detection ability of an elevated duct captured by radiosonde. The atmospheric humidity is measured through vibration-rotation Raman scattering signal, and the atmospheric temperature is measured through pure-rotational Raman scattering signal. Together with atmospheric pressure measured by radiosonde, the atmospheric refractive index can be calculated. Signal fluctuation with Poisson distribution is added in the four detection channels of raman lidar system, in order to accord with actual detection process. The emulation results indicate that, the medium-sized lidar possesses considerably good capture ability towards the weak elevated duct. In addition, the identification probability, layer thick and strength of elevated duct detected by lidar with different temporal and range resolutions are surveyed based on the MC method.
