【Abstract】 On the condition of the underwater acoustic signal, the perturbed amplitude would be small, and then the general hydrodynamic equations may be linearized. On the basis of this approximation, the dispersion relation and the form of the water surface horizontal miniwave are obtained. The results show that the water surface horizontal miniwave has the characteristics of shorter wavelength and lower velocity, therefore it can modulate the light intensity of the incident laser beam on the water surface, which provides the theoretical basis for the detection of underwater signal.更多还原
