| 摘 要： | 以运动坐标系中的海浪谱为靶谱应用静止坐标系中随机波面的模拟方法─—线性叠加法和线性过滤法模拟匀速运动坐标系中的随机波面，给出了两种方法的原理及模拟手续。通过模拟实验发现，在高速运动的坐标系中线性叠加法优于线性过滤法，在低速情形，线性过滤法好于线性叠加法，并在模拟技术上给出了各参数的选取方法。

| Abstract: | With the sea wave spectra in a moving coordinate system as target spectra,the random sea waves in a moving coordinate system are simulated by using themethods presented for a static coordinate system, namely, the component method and the filter method. Through comparing the examples, it is found that in the case of a high velocity moving coordinate syetem the component method is superior to the filter method, while in case of low velocity, the situation is reversed. Meanwhile, the methods of selecting the technical parameters are dealt with as well. |
