| Abstract: | On the basis of the theory of the propeller sheet cavitation noise radiation, this paper proposes a method for inversion of ship propeller noise radiation for the non-uniform wake field behind a ship. The Markovian estimation of the wake field parameters defined in the paper is obtained, and the existence and uniqueness of the solution of the inverse problem is discussed. |
