Abstract

Abstract

To better understand and utilize the acoustic field in shallow sea, a theoretical method that can give the full-wave solution is proposed, then the complex integral expression of the acoustic field is given. The complex integral fraction is solved in the complex plane, and the components of the acoustic field in shallow sea are obtained. The high-order staggered grid finite difference method is also used to numerically simulate the acoustic field in shallow sea, showing the wave field structure and spatial energy distribution. Results show that the acoustic field in shallow sea includes discrete spectrum and continuous spectrum; The discrete spectrum includes normal waves and Scholte wave, and the continuous wave includes lateral waves; The amplitudes of normal waves and Scholte wave are inversely proportional to the root of horizontal propagation distance, and the amplitude of lateral wave is inversely proportional to the power of horizontal propagation distance; The shallower the sea water, the lower the frequency and the greater the depth of the sound source, the less energy in the sea water will be. The energy radiated by the acoustic source is mainly propagated in the form of Scholte wave, and the energy is mostly concentrated at the seabed interface.
