procedure for determining the characteristics of sources of spread hit by a wave, particularly for lidar systems for the study of atmosphere and relative device

摘要

The probability distribution of the dimensions of scattering sources is calculated by the measurement (5 to 7) of their coefficient of attenuation for several wavelengths. In the case of sources having the same dimensions, the probability distribution of any other stochastic variable connected with the scattering process can be calculated. The preferred application is in lidar techniques for the remote measurement of the distribution of the dimensions of aerosols in the atmosphere, and in particular of water droplets in clouds, by the analysis of the intensity of the back scattering.
