Research on Bionic Perception Technology Based on Flow Field

Aiming at the research of underwater detection technology based on the information of relative motion flow field between underwater objects, firstly, theoretical analysis is carried out, through the modeling of underwater moving objects, the abstract modeling of obstacles is carried out, and the characteristics of flow field around underwater moving objects are studied by hydrodynamics, and the distribution characteristics of geometric and physical parameters of flow field are systematically analyzed. The driving law of characteristic parameters on the flow field and the interference effect of obstacles on the flow field around the moving body are obtained. The correlation between the characteristic parameters of obstacles and the characteristics of the flow field around the moving body is obtained, and the judgment criteria for detecting obstacles are formed.
