| 摘 要： | 介绍了估计二阶谱的TOR方法,较合理地确定了TOR方法中AR模型的阶数,并首次将其应用于实际海浪过程的二阶谱估计。结果表明,用TOR方法对较短的波面序列进行二阶谱估计时,明显优于传统的周期图方法。

| Abstract: | The TOR method for estimating bispectra is described in detail. The order of AR model for the estimation of ocean wave bispectra is reasonably chosen by comparison with the period-gram approach and by use of the characteristics of bispectra. The method is here applied to ocean wave bispectra for the first time. It is shown that the resulted bispectra are obviously superior to the ones by the periodgram approach when data records are short. |
