Abstract

According to the theory of underwater acoustic spread and circular piston transducer array, the mathematical model for the directivity of array is created. By means of MATLAB, the accurate expression method for the figure of array directivity is studied, and the characteristic and difference of the simulation curve in various direction are analyzed. It is shown by the application that, to a certain extent, the conclusion has practical value and guide meaning for the directivity simulation and design of the array.
