Abstract

The horizontal-longitudinal correlations of sound field at large depth in the direct zone of deep water have important reference significance for the design of horizontal array and the signal processing of array. The characteristics of deep water sound transmission loss and horizontal-longitudinal correlations are analyzed based on a deep water incomplete channel sound transmission experiment in the South China Sea in the winter of 2016. The horizontal-longitudinal correlations in deep water of the direct zone are analyzed through theory and simulation. The results show that the horizontal and longitudinal correlation radii of sound field at large depth are independent to the sound energy. The interference characteristics of sound field at large depth in deep water of the direct zonelead to the existence of oscillation structure of horizontal-longitudinal correlation coefficient. The horizontal-longitudinal correlation radius of sound field is consistent with the oscillation period of sound transmission losses. The longer the oscillation period is, the larger the horizontal-longitudinal correlation radius is. The horizontal-longitudinal correlation radius decreases with the increase in the frequency and depth of sound source in the direct zone. The horizontal-longitudinal correlation radius of sound field at the near distance from direct zone is less affected by the change of receiver depth, but it increases with the receiver depth at a far distance.
