Spaceborne synthetic aperture radar is one of the important means of detecting ocean internal waves, and sea surface wind speed has a significant impact on the ability of synthetic aperture radar to detect ocean internal waves. Based on the theory of the influence of sea surface wind speed on the ability of synthetic aperture radar to detect ocean internal waves, combining the insitu measured parameters of ocean internal waves, additional with the corresponding ocean environment and synthetic aperture radar data, this paper analyzes the imaging mechanism of ocean internal waves on synthetic aperture radar images, discusses the different manifestations of upward and downward ocean internal waves, and elaborates on the ability of synthetic aperture radar to detect ocean internal waves under the combined influence of internal wave amplitude, thermocline depth, and thermocline intensity under different wind speed conditions. Simulation analysis shows that the smaller the sea surface wind speed, the larger the internal wave amplitude, the shallower the thermocline depth, and the stronger the thermocline intensity, the stronger the ability of synthetic aperture radar to detect internal waves in the ocean. The results can provide technical support for the planning of satellite observation tasks in the early stage of detecting ocean internal waves using spaceborne synthetic aperture radar.
