spacial frequency 中文意思是什麼
spacial frequency
解釋
空間頻率-
At first some modification is made in conventional beam forming of frequency domain, namely to estimate doa by arrays outputs on compensated spacial frequency points of echoes. then the cwt is utilized to signal processing in space - frequency domain for estimation of doa, and the corresponding modification is also made. in the dissertation, the computer simulations of doa estimation for both narrow - band and wide - band echoes are given, so do the necessary comparison among several methods and crb
首先在傳統的頻域波束形成演算法的基礎上，提出對寬帶信號的頻率補償，也即對寬帶回波信號的各空間頻率根據時間頻率的差異進行相應補償，然後對各陣元輸出求和來得到方位估計；其次將連續小波變換引入到空間?頻率處理中，從而完成對目標方位的估計，並進行了相應地補償。 -
The process that light wave gets through arrayed waveguides can be regarded as a process of extracting spatial sample and filtering spatial frequency. spacial sample is accomplished by period interval arrangement of awg and spatial frequency filtering is accomplished by the fundamental mode and phase delay of each arrayed waveguide which is just a spatial frequency filter
而光場通過陣列波導的過程，可八碩士學住論文waiaster 』 stiesis以看作是空間抽樣以及空間濾波的過程：空間抽樣由陣列波導的周期間隔排列完成，空間濾波由每個陣列波導的基模形式以及位相延遲完成（陣列波導即為一空間濾波器） 。 -
On the basis of the calculating of complexity ( c value ) and combination entropy ( h value ) from the numerical method of geoanomaly analysis, logged signals data ( spontaneous potential, acoustic slowness, spontaneous gamma ray and electrical resistivity ) and seismic data ( amplitude, frequency, phase, etc. ) are processed after regularization of data obtained from linqing basin of shengli oil field. many types of geoanomalies obtained from the computation are analyzed so the spacial variation rules of them can be discovered. then the oil regions can be predicted by this method
本文創新性地將地質異常概念引入油氣勘探領域，以地質異常理論為指導，以勝利油田臨清坳陷油氣地質異常預測研究為例，針對我國陸相含油氣盆地的常規測量、測試和解釋數據，如與地震相關的數據（振幅、頻率、吸收系數、層速度等） 、與測井相關的數據（自然電位、聲波、視電阻率、自然伽馬等）等，提取不同數據類型的地質異常以及異常組合特徵，通過對這些參數的綜合研究分析其空間變化規律，系統地建立有效預測油氣藏的新技術和新方法，進而達到區域油氣資源預測的研究目的。
