High resolution remote sensing imaging simulation technology for sea surface target has been widely used in sea surface target detection and recognition. The interaction between ship and seawater can be seen in high resolution, and the radiation simulation of complex flow field is the main difficulty of imaging simulation. The geometry and physical properties of the flow field generated by the interaction between the ship and the sea during navigation were studied, and the coupling model with the radiation characteristics of the sea surface was proposed. The three-dimensional model of sea surface was constructed by the method of spectrum analysis, and the three-dimensional model of ship navigation flow field was constructed by the method of computational fluid dynamics. According to the different distribution of sea surface components, the radiation characteristics were associated with the three-dimensional structure, and the three-dimensional radiation model of sub meter ocean scene was constructed. Through radiative transfer calculation, multiple reflection simulation in the scene, atmospheric influence and sensor effect simulation, the satellite remote sensing image under the observation condition was finally obtained. The results show that the mean error and standard deviation error of GF-6 satellite images are 9.17% and 9.21% respectively, which are compared with the simulated images under the same imaging conditions. The average gray value, gray distribution and texture details of the images are consistent, which can simulate the ocean target scene under high resolution satellite imaging.
