Estimation and Optimization of Vertical Array Shape in Steady Uniform Flow

Abstract

In use of vertical array to measure underwater target sound signal, the shape of vertical array is changed by current, the offset angle can be reduced by hanging a heavy object or by add fairing around floating body or by add roughness on vertical array surface . The model to predict the line style in stream is dealt with in this paper. Different method and iteration algorithm are used in the mode, and an underwater acoustic method is given to monitor the line style in real time. Both of the predict model and the method of monitor are used in a practice test, and the result illustrates the accuracy of the predict model and its utility in the design and application of vertical array.
