Abstract:
The Monte Carlo method is used to model the operation of the multifrequency satellite lidar Tektonika-A, designed for detection of aerosol inversions in the atmospheric boundary layer. Estimates are obtained for the wavelengths l = 1.06, 0.53, and 0.35 mkm (the three harmonics of the Nd:YAG laser) and boundary conditions corresponding to real parameters of the receiving-transmitting lidar system. The basic optical model was chosen to correspond to the background state under the assumption of a stratified inhomogeneity. The model can be generalized to include aerosol inversions of any origin, whether natural or anthropogenic. The obtained results provide information on the dynamic range of the return signal in a given spectral interval for different optical situations. In addition, we determined limiting levels of noise of active origin and caused by outgoing radiation under different optical and geometrical conditions of operation of the lidar system.
