In the study of directional spectrum and reflection coefficient of multidirectional wave , firstly the wave elevation trains overlapped by the incident wave and the reflected wave of multidirectional wave are simulated in the method of a frequency corresponding to a direction . then the composed wave trains are analyzed respectively by the mbdm and the mmlm . during the numerical study , the input factors include the various wave parameters , the different measuring wave system and the various reflect characteristic 在多向不規(guī)則波入射波方向譜和反射系數(shù)的分析研究中,利用方向頻率對(duì)應(yīng)法模擬了多向不規(guī)則波入射波與反射波疊加的波面序列,將此合成波列分別應(yīng)用mbdm和mmlm進(jìn)行分析,通過輸入各種波浪參量、不同波浪測(cè)量系統(tǒng)和各種反射特性等因子,檢驗(yàn)了mbdm和mmlm方法的適用條件,對(duì)兩種分析方法的性能進(jìn)行了比較分析。
