In the analysis of the frequent spectrum and the reflection coefficients , based on goda ' s two - points method which fit to the normal incident wave , a modified two - points method is derived that can be used to calculate the frequent spectrum and reflection coefficient of the oblique waves from which the frequent spectra of incident waves and reflected waves incoming in arbitrary angular , the bulk reflection coefficient and the frequent spectrum of reflection coefficient could be computed , also from which in theory the waves could be measured in two wave gauges which is disposed at any direction 為了分析單向不規(guī)則波入射波的頻率譜和反射系數(shù),本文在goda用于分析正向不規(guī)則波的兩點法的基礎上,提出了可用于斜向不規(guī)則波頻譜分離及其反射系數(shù)計算的改進兩點法,該方法可用于計算任意波浪入射角的入、反射波譜、總體反射系數(shù)和反射系數(shù)的頻率譜,并且測量波浪過程的兩浪高儀可在較廣的方向范圍內(nèi)布置。
The method has been used to separate the frequent spectra of incident waves and reflected waves of the composed wave that are simulated by a numerical method . the results shown that the frequent spectra of incident waves and reflected waves being computed are consistent with the target spectrum and the bulk reflection coefficient is too . the frequent spectrum of reflection coefficient is same as the input round the peak frequency 將此方法用模擬合成波波列的分離計算,結果表明,分離的入、反射波頻譜與輸入的靶譜符合良好,且計算的總體反射系數(shù)與輸入的總體反射系數(shù)一致,計算得到的反射系數(shù)頻率譜在峰頻附近與輸入值符合良好,說明該分析方法是可靠的。
