Acoustic and radio-acoustic remote sensing studies in C.I.S. (Former U.S.S.R,)-current status

This paper presents brief review of studies carried out in the U.S.S.R. from about 1940 to 1960, which serve as the basis for methods of probing the atmosphere by directed sound waves. The remote sensing techniques developed in the U.S.S.R. are described. A summary of some theoretical and experimental results, as well as the results of applying the sodars and rasdars (RASS) to studies of the atmospheric boundary layer in the 1980s are also given
