Pohrebennyk V. Мethods and measuring systems for operative determination of sntegrated parameters of water and bottom sediments

The thesis is devoted to development of new methods for construction of information-measurin systems for operative determination of integrated parameters of water envirioment and bottom sediments. Methology for the solving of given tasks which take into account linear and nonlinear effects of the interaction between acoustic waves and investigated environment and the establishing of new informative parameters for multiple reflected signals has been created. The new robust methods for measuring of tempporal and amplitude values of acoustic impulse signals on the base of integral transform has been suggested. The main results of the thesis have been implemented in the institutions and organizations.
