摘　　要：基于管长龙等（１９９５ａ，ｂ）的扩展本征矢方法，提出了可用于入射波和反射波共存浪场能量方向分布的估计方法，并给出了直接计算反射率的公式。数值模拟结果表明，此方法大大改善了原有方法的估计精度。Based on the extended eigenvector method (EEV) derived by Guan et al. (1995), a modified method (MEEV), in which the reflection coefficient can be calculated directly, is proposed as a general and practical method for estimating directional spectra in an incident and reflected wave field. The results of the numerical simulations show that the MEEV is superior to the EEV in resolution power, and the computed reflection coefficient agrees well with the input data within a certain range of incident directions.
