N2 - The complex underwater environment and the development of deep-sea target "stealth" technology put forward higher requirements for the detection technology of high-speed vehicles, so it is important to carry out the study of flow field detection and characteristic analysis. In order to study the characteristics of the flow field around a high-speed vehicle under actual conditions, a numerical calculation model of the high-speed vehicle sailing with a given motion trajectory was established. Based on the finite volume method to simulate the simulation method of detecting underwater high-speed moving targets in actual engineering, the dynamic water pressure time history curves at different speed conditions and monitoring points at different locations were calculated and analyzed. The results show that the attenuation law of underwater flow field at different depths is consistent with the increase of the velocity of high-speed vehicle. At the same depth, the main frequency characteristics of water pressure signal are consistent. With the increase of vehicle speed, the main frequency amplitude increases by 10%~15%. The simulation results use the hydrodynamic information of the flow field to realize the parametric description of the flow field around the underwater target, and provide a new idea for underwater detection technology.
