摘    要:利用多个波高仪解决了两点法间距取值局限性的问题,利用FFT实现了波浪三角级数展开式系数的快速运算。改进的两点法可以分离规则波和不规则波,本文首先分离叠加噪声的计算机模拟合成波浪,分离精度利用相关系数评价,然后测试无反射造波水槽中的现场合成波浪,经波谱分析,分离精度能够达到工程标准。

关 键 词:两点法  入反射分离  波高仪  相关系数

Abstract:This paper solves the problem of the limitation of sensors' distance of two point method by several wave sensors,and implements fast calculation of the coefficient of trigonometric series expanded formula by FFT.The improved two point method can separate the composite regular and irregular waves into incident and reflected waves.Firstly,the result of separation of the composite waves which adds noises is evaluated by coefficient correlation.Then the real composite waves in the non-re-reflected wave-making flume are considered.Analysis of wave spectrum shows that the precision of separation is high,and satisfy the needs.
Keywords:two points method  separation of incident and reflected waves  wave sensor  correlation coefficient
