動態調整權重的光譜匹配測度法分類的研究Doing the further research on the division frequency stack on the foundation of study of predecessor, at first the residual moveout correction is done to the seismic record, make the phase axle regularity, doing foundation for the same phase stack ; then carried on division scale processing by wavelet transform ; spectrum whitening is done to each scale, the high and low frequency band need to do prolongs, the middle frequency bands only increase the value of the frequency spectrum ; several kinds of methods that estimate the value of signal - noise ratio has been studied further, and summarize their advantage and disadvantage as well as the scope of application ; the seismic record after spectrum whitening is stacked by weighting with the value of the signal - noise ratio ; then estimate the value of signal - noise ratio which is each scale section after stacking, the scale that the signal - noise ratio is big is assigned big weighting, otherwise, the scale that signal - noise ratio value is small is assigned small weight ing, and carried on weighted reconstruct to each scale section
本文在前人研究的基礎上,在分頻疊加方面做了進一步的研究。首先對地震記錄進行剩餘時差校正,校齊同相軸,為同相疊加做好基礎工作;然後對地震記錄用小波變換的方法進行分尺度處理;對各個尺度分別做譜白化,對于高、低頻段需要做頻帶延拓,中間頻段僅提升頻譜值;對于幾種信噪比定量估計的方法進行了深入的研究,並且總結了它們的優缺點以及適用范圍;對譜白化后的地震記錄用信噪比估計值作為加權系數進行加權疊加;對于各尺度的疊加剖面也進行信噪比估計,對于信噪比大的尺度給予大的加權系數,反之,信噪比值小的尺度給予小的加權系數,對各尺度疊加剖面進行加權重構。Secondly, the relativity of the speech signal and that conducted by bone and the relation between the spectrum and timbre were analyzed, so some regulations were discovered. based on correction of spectrum, a method for speech reconstruction was proposed. thirdly, the power constant was obtained by large quantity statistic experiments
文中分析了骨導信號和語音信號的相關性,以及頻譜與音色的關系,發現了其中的一些規律,提出基於譜修正的語音重構,並通過大量統計實驗,得到骨導信號譜修正的權系數。In the first part, the research progress of cloud motion wind was introduced and the significance of the 1 - d fourier analysis technique was given. in the second part, based on fluctuation theory and fourier analysis, the one dimension fourier analysis technique on cloud motion winds is deduced and demonstrated theoretically. by simulating mathematically on frequency and on space, we not only uncovered two questions in practice, first is phrase folding, second is frequency spectrum overlapping, but also gave methods and suggestions to solve them or avoid them
本文由六章組成,第一章介紹雲導風技術的研究進展和傅立葉導風技術的研究意義;第二章以波動理論和傅立葉變換為基礎,對傅立葉相位導風技術進行理論推證和誤差分析,通過模擬分析了空間域和頻率域的導風特點,揭示了在導風過程中出現的相位重疊和頻譜混疊兩種現象;第三章通過計算在空間域速度線性變化情況下頻率域振幅權重平均速度(5 ) the atmospheric noise of interferogram is a fractal process, whose spatial spectrum exhibits the characteristic - 8 / 3 powder law behavior associated with turbulence phenomena. the effects of this 1 / / process to insar dem were anylysised and the error power of noise and atmospheric term were estimated for weighted combination of multi - temporal insar data. the test results showed this data fusion process can improve the accuracy of insar dem
