Directional Wave Spectrum and Reflection Coefficients in Incident and Reflected Wave Field

本文采用数值模拟波浪和物模试验的方法,对采用多种仪器和改进的贝叶斯方法(MBDM)观测和分析入、反射波共存场中多向不规则波的方向谱和反射系数进行了验证.结果表明:浪高仪阵列可测得较好的结果;MBDM基本上能分辨波浪的方向分布,在波能的主要分布范围内,算得的反射系数与输入值也基本一致.

This paper describes the determination of the directional spectrum and the reflection coefficientsin incident and reflected wave field with laboratory measurements and the modified Bayesian approach (MBDM). It is shown that wave gage array method is better and the MBDM can be effectively used to distin-guish the directional spreadng and the obtained reflection coefficients satisfactorily agree with the target values in the directioual range of main wave energy.
