Abstract
The clouds signals of the 'Balkan-1' space lidar, intended for cloud sounding, were instated using the Monte Carlo method. The calculations are carried out for the wavelength (lambda) equals 0.532 nm and specific parameters of orbit and the lidar. The clouds of homogeneous and inhomogeneous structure in the cloud layer (Delta) H equals 100 m is given depending on the opto-geometric experimental conditions. From the analysis of the result it follows that the main parameter, determining the signal structure, is the optical thickness of the sounded cloud layer. The viewing angle, the scattering phase function have no effect on the amplitude and the space-time signal characteristics. For inhomogeneous clouds the lidar signal repeats qualitatively the extinction coefficient profile if the layer optical thickness is less than 2.5-3.0.
