摘　　要：在处理声学测波仪数据时,由于潮位的影响而使计算得到的波浪特征值不准确,基于此问题,本文介绍了自适应滤波及自适应噪声抵消的基本原理,并将这种方法引入到波浪数据处理中,通过大量的实验数据比较证明这种处理方法是可行的。During the data processing of acoustics wave gauge, the calculation of wave characteristics are not accurate due to the influence of tide. Regarding this problem, the article introduced the basic principle of adaptive filter and adaptive noise cancellation, which were inducted to the wave data processing. This processing method is feasible by large amount of testing datas.
