在多向不規則波入射波方向譜和反射系數的分析研究中，利用方向頻率對應法模擬了多向不規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用mbdm和mmlm進行分析，通過輸入各種波浪參量、不同波浪測量系統和各種反射特性等因子，檢驗了mbdm和mmlm方法的適用條件，對兩種分析方法的性能進行了比較分析。For the purpose of determining the fine structures and deleting interferences in solar radio spectra, we introduce a data processing method with the combination of wavelet transform and channel - modification. firstly, the original data were divided by the each mean value at each channel, which can clean a large part of horizontal branch of grid - texture on spectrum. secondly, wavelet transform was applied to the result by the first step
為此，我們首先引入了「通道歸一化」方法，它可以有效地消除網紋結構中的橫條紋，緊接著，再對第一步處理結果實施小波濾波，結果證明，兩種主要方法的聯合應用能夠有效地去除疊加在太陽射電頻譜圖中的網紋結構和其他噪聲，得到清晰的頻譜圖。The differences between this method and other similar methods are : ( 1 ) the fast synthetic source record algorithm based on the wave theory is adopted in prestack depth migration. ( 2 ) the plane wave source is used in migration that is consistent with the velocity analysis method. ( 3 ) by using the controlled illumination, the distortion of the plane wave source wavefield due to the lateral velocity variation is avoided therefore the error of velocity analysis is reduced and ( 4 ) the practical velocity spectrum makes the interactive migration velocity analysis feasible and convenient
與其他類似偏移速度分析方法的不同點在於： （ 1 ）疊前深度偏移採用基於波動理論的快速合成震源記錄演算法； （ 2 ）偏移方法採用平面波震源，與速度分析方法一致； （ 3 ）應用控制照明技術，避免了因橫向變速而導致的平面波震源波場在傳播過程中的畸變，從而減小了速度分析的誤差； （ 4 ）實用的速度譜設計，使交互偏移速度分析可行且易於操作。In the dissertation, an in - depth study is carried out by the author by synthesizing multi - disciplinary knowledge on the following topics : the abstraction of weak spectral signal, the optimal pathlength measurement condition, the optimization of regression method, the enhancement of multivariate calibration model robustness and the physical explanation of measurement results are studied
