船舶螺旋桨空化噪声辐射的逆问题

Inverse problem of ship propeller cavitation noise radiation

本文以螺旋桨片状空泡噪声辐射理论为基础，提出一种由螺旋桨空泡噪声辐射反演船后不均匀伴流场的方法，获得了所定义的伴流场参数的马尔可夫估计。文中探讨了此逆问题解的存在性与唯一性。

On the basis of the theory of the propeller sheet cavitation noise radiation,this paper propose a method for inversion of ship propeller noise radiation for the non-muniform wake field behind a ship.The Markovian estimation of the wake field parameters which are defined is obtained. And the existence and uniqueness of the inverse problem is discussed.
