傅里葉合成法-
This method is easy to implement and has no restriction on array geometry and sensor patterns ; three methods for the design of broadband frequency invariant beamformer are proposed, which are the method of resampling signals received by the array, the dft ( discrete fourier transform ) interpolation method and adaptive synthesis method, respectively. examples and performance analyses are given for each method ; a simplified linear constrained minimum variance broadband adaptive algorithm that based on dft interpolation method is presented. compared with conventional broadband adaptive algorithms, the presented method can reduce computation work greatly
提出了一種簡單、易於實現的恆定束寬波束形成器設計方法，該方法對陣形和陣元指向性沒有任何限制；分別提出了基於陣列接收數據重采樣、基於dft插值和自適應綜合的三種具有頻率不變波束圖的寬帶波束形成器設計方法，對于每一種設計方法都給出了一個設計實例並做了性能分析；提出一種基於dft插值的簡化線性約束最小方差寬帶自適應陣列演算法，該方法可以大大降低自適應陣列的運算量。 -
Lastly, aiming at the poor results which all current algorithms do for directional textures, and cannot synthesis texture directly, aiming at the particularity of this kind of textures, we bring forward the conceptions of non frontal parallel textures and frontal parallel textures. by analyzing texture ' s direction through fourier spectrum, we introduce the conception of main direction, and solve the approximation value of texture ' s main direction by discrete approximated approach. by this way, we can synthesis indirectly simple structural non frontal parallel textures
最後針對現有演算法對帶有方向的紋理合成效果差，無法直接合成紋理圖像的難點，本論文首先提出了非正平行紋理與正平行紋理的概念，分析了它們之間的內在聯系，引入了兩個角度參數來描述紋理的朝向，採用傅立葉頻譜法分析紋理的方向特性，並提出了紋理主方向的概念，本論文引入離散逼近的方法來求解出紋理主方向的近似值，這樣我們就能用一種間接的方法合成簡單的結構性非正平行紋理。 -
Antialiasing in two - dimensional texture mappings is also discussed including a modified summed - area table algorithm. three - dimensional texture mappings are summarized including several procedural texture functions and fourier synthesis techniques

The wavelet analysis is applying widely to pure mathematics, applied mathematics, signal processing, speech recognition and synthesis, automation processing and image analysis etc. the key advantage of the wavelet analysis is that, in contrast to the conventional fourier analysis, it can be localized in the time and frequency domain simultaneously
小波分析已經廣泛應用於理論數學、應用數學、信號處理、語音識別與合成、自動控制和圖像處理與分析等領域。同傳統的傅立葉分析相比，小波分析的最大優勢在於可以同時在時頻兩方面實現局部化分析。
