| 摘 要： | 海水温度剖面在水声学领域扮演着重要的角色,而目前大面积实时温度剖面测量能力尚存不足,因此对于海水温度剖面的网格插值研究就有一定的意义。基于普通克里金法对某海域获得的剖面样本进行插值,通过逐点逐面的拟合最终得到该海域三维温度场。通过拟合温度剖面和部分样本剖面的对比,证实普通克里金法对于海水温度剖面拟合具有很好的效果,具有应用的可行性。

| Abstract: | Seawater temperature profile plays an important role in underwater acoustics, while the ability of acquiring instant temperature profile in a large area is far from sufficient. Based on MATLAB, the Ordinary Kriging method is used to interpolate profiles acquired from a certain sea area point-to-point and surface-to-surface into a three-dimensional temperature field. Contrasting the interpolated profiles with the acquired ones, the OK method is tested to be effective for fitting the temperature profile with highly feasibility. |
