对于短峰波，推导了利用多点实测资料预报波浪的公式。该公式不仅适用于平稳过程，也适用于非平稳过程。在此基础上，得到了多点测量与目标点预报之间自由面高程关系的卷积积分公式。长峰波的数值实验表明，当预报时间较短且测量点距离目标足够远时，预报误差较小。虽然它被发现，所提出的方法的基础上的预测精度有一个限制短峰波，协议是相当不错的。
The formulation for wave prediction using multipoint measured data is derived for the short crested waves. The formulation can be applied not only for the stationary process but also the non-stationary process. Based on this formulation, a convolution integral formula which represents the relation of free surface elevation between multipoint measurement and target point prediction is obtained. Examples based on numerical experiments of long crested waves show that prediction error is small when the prediction time is short and the measurement point is sufficiently far from target. Although it is found that the accuracy of the prediction based on the proposed method has a limit for short crested waves, the agreement is fairly good.
