摘要
根据线性系统理论，首先由给定的靶谱模拟海浪信号，再把此信号转换为造波控制输入信号，最后在水槽中指定的截面处产生具有给定靶谱的随机波。这种模拟方法已在青岛海洋大学物理海洋实验室的大型水槽中实现，并取得良好的效果。
According to the theory of linear system, a method is proposed to simulate a random wave signal with a target spectra and then transform it to a voltage signal, which is used to control the movement of the wave maker to produce random waves with the target spectra at an assigned section in the wave tank. This method has been successful in the wave tank of the Physical Oceanography Laboratory, Ocean University of Qingdao. The comparison between the target spectra and the measured spectrua shows good agreements. And the statistic characteristics of the measured waves are closely consistant with those calculated from the corresponding target spectra.
