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 linear system theory, the ocean wave signal is first simulated by a given target spectrum and then converted into a wave control input signal. Finally, a random wave with a given target spectrum is generated at a designated cross section in the tank. This simulation method has been implemented in the large-scale sink at the Qingdao Ocean University Physical Ocean Laboratory and achieved good results.
