摘　　要：为了获取海上波浪谱实时观测数据,来满足日益增长的海洋监测预警、海洋工程、海洋学研究等对精细化海浪过程数据的需求,设计了一种基于微机电系统MEMS运动传感器的波浪谱实时获取装置—“前哨”浮子,解决了波浪谱反演算法、基于北斗短报文的波浪谱传输等关键问题,实现了波浪谱实时观测。通过开展浮子与DWR-MkIII型波浪骑士的海上比测,结果表明:二者的一致性非常好,该浮子能够实时、准确地观测波浪谱。In order to obtain the real-time observation data of ocean wave spectra and meet the increasing needs of marine observation and monitoring,ocean engineering,oceanography research and other requirements for high-resolution of wave process data.A real-time acquisition device of wave spectra based on Micro Electro Mechanical System(MEMS)motion sensor-“Outpost”float is designed,which solves some key issues such as wave spectra inversion and wave spectra transmission based on Beidou short message,and then realized the real-time observation of wave spectra.The comparative test between the float and the DWR-MkIII Waverider is carried out,the results show that the consistency of them is very well,and the float can accurately observe the wave spectrum in real time.
