Abstract

Abstract

In the process of navigation, the ship will produce the wake region, and the scattering phenomenon occurs when the laser passes through the wake region of the bubble. Through the detection and analysis of the scattered light, the ship can be detected and identified. In this paper, the influence of the wake bubble curtain on laser transmission characteristics was investigated, and the light intensity changes of the wake bubble curtain were detected based on a fiber optic spectrometer. The experiment simulated the light intensity change of the wake bubble curtain with a thickness of 10 cm and 15 cm under different pressures at 5, 15, and 20 cm away from the water surface and explored the variation of intensity of forward and backward scattered light with pressure. The experimental results show that with the increases in pressure, the variation of light intensity slows down, and the concentration and the radius of the bubble increase. Higher bubble concentration indicates a smaller variation of light intensity. With the increase in pressure, the intensity of forward scattered light decreases linearly, and the intensity of backward scattered light increases.
