摘　　要：跨介质航行器出水过程中存在多相流、空泡非定常演化、强瞬态效应及载荷环境突变等特征,对航行器的稳定航行、出水姿态和结构强度有着显著影响。为充分认识和验证航行器在海洋环境下的出水性能,需发展与其工况相适应的水下信息获取技术。文中总结了跨介质出水航行器试验中的目标定位、景象观测、环境测量及跨介质信息传输等水下信息获取技术研究现状,分析了高动态以及大深度等新质跨介质航行器发展对水下信息获取技术提出的新需求,展望了其体系化、多模化和数字化发展趋势,为探索解决水下高价值信息获取难题,以及更深入掌握水下复杂环境和解译水下关键过程提供思路和技术上的参考。The water exit process of trans-medium vehicles involves multiphase flow,unsteady evolution of cavitation,strong transient effect,and varying load environments,which significantly affects the motion stability,water exit attitude,and structural strength of the vehicles.To fully understand and verify the performance of the vehicle during water exit in the marine environment,underwater information acquisition techniques adapting to the corresponding working conditions are urgently required.In this paper,the research on underwater information acquisition techniques for the water exit test of the trans-medium vehicle was summarized,such as target localization,phenomena observation,environmental measurement,and trans-medium information transmission.Meanwhile,the new requirements for underwater information acquisition techniques to adapt to the modern trans-medium vehicles with high dynamics and large depth were analyzed,and its development trend towards systematization,multimodality,and digitalization was prospected,which may provide an idea and technical support for obtaining the high-value underwater information,understanding the complex underwater environments,and interpreting key underwater motion process.
