| 摘 要： | 针对现有GPS海浪测量技术的不足，提出基于TRACK的GPS海浪测量方法，即利用TRACK解得海上载体高精度的垂向位移，经浪潮分离提取海浪信号，采用周期图法估计海浪信号的功率谱，计算海浪要素。利用实测数据进行实验，结果表明，平均波高和平均周期与测波仪结果差异分别小于2 cm和0.25 s，验证了本文方法的有效性。

| Abstract: | Aiming at improving the limitations of existing GPS wave measurement technologies, a GPS wave measurement method using TRACK is presented| specifically, acquiring high-precision vertical displacement of carrier on sea surface via TRACK, then deriving the wave signal from the vertical displacement time series, estimating the signal power spectrum using periodogram method, and figuring out the wave elements. Using the measured data for experimental purposes, the results show that the differences of average wave height and average period are within 2 cm and 0.25 s compared with the results of wave gauge, confirming the feasibility of the proposed method. |
