Abstract

The invention relates to a method for obtaining the light scattering coefficient of sea wave foam with high realistic feeling, comprising: obtaining sea wave parameters; establishing a sea wave motion model according to the sea wave parameters to obtain the wave height field distribution; superimposing sea waves according to the sea wave height field distribution The foam distribution model is used to obtain the mixed state distribution of the sea foam; according to the mixed state distribution of the sea foam, the vector radiation transfer equation is solved to obtain the light scattering coefficient of the sea foam. The present invention starts from the construction of the wave height field, considers the influence of different sea conditions, weather conditions, different foam sizes and mixing ratios on the propagation of light in the foam, establishes the dissolution model of the wave foam in the mixed state of bubbles and water droplets, and generates the wave foam under different mixing modes The physical model of the sea foam is the mixed state distribution of the sea foam, and then the vector radiation transfer equation is constructed to realize the real-time calculation of the light scattering coefficient of the sea foam.

Description

technical field [0001] The invention belongs to the field of marine physics, and in particular relates to a method for obtaining the light scattering coefficient of high-realistic ocean wave foam. Background technique [0002] With the improvement of multi-dimensional photoelectric detection methods, the demand for real-time acquisition and processing of photoelectric characteristic information of sea surface is increasing. Wave foam is a common natural phenomenon on the sea surface. Since the existence of wave foam can seriously affect the optical properties of the sea surface, it is an important basic research to explore its light scattering properties. Under the influence of a certain wind speed, the broken waves are mixed with the air, and a part of the foam cover will be formed on the sea surface. According to observational experiments, when the wind speed is greater than 7 m / s, white water will be produced on the ocean surface, which is called sea wave foam, also know...
