The research regarding the liquid water content of clouds is quite important for the study of physical processes in the atmosphere, and development of ice protection system. The paper analyzes the possibilities of using the active-passive sounding method to restore the vertical profile of cloudiness with the use of measurements of its radio brightness temperature and radar data on its power. A description of the algorithm for processing radar and radiometric data, and the technical characteristics of the radiophysical active-passive sounding system is given. Also, the results of experimental studies of the water content profile for layered clouds obtained by the joint processing of radar and radiometer data at a wavelength of 3.2 cm and 0.8 cm are presented.
