時變反褶積 的英文怎麼說
中文拼音 [shíbiànfǎnxíjī]
時變反褶積
英文
time variant deconvolution-
In order to improve the prospecting precision to the earth of transient electromagnetic method ( tem ), the idea of tem imaging is proposed according to the characteristics of both electromagnetic wave propagation and response : the wave - impedance is calculated from observed data in - field by the way of inverse - faltung and linear digital filter ; the sequence of reflection coefficients corresponding to every tiny - lever move time is calculated by the way of linear programming, and the imaging result section is drawn consequently
摘要?提高瞬變電磁法的對地探測精度，從瞬變電磁場的傳播特性和電磁響應特性兩個角度?慮，提出了瞬變電磁成像方法：由野外實測磁場感應數據，經過反褶積和線性數字濾波求出波阻抗；用線性規劃法求出每一微層走時所對應的反射系數序列，並以此?參數繪製成像結果圖。The algorithm used in the past was usually based on fourier transform, but there are clearly limitations in the method, because the seismic amplitude spectrum that it evaluated is the function of time windows
如果所選時窗過短，振幅譜會與變換窗函數褶積，失去頻率的局部化特徵，而且過短的時窗會使子波的旁瓣呈現為單一反射的假像。According to the seismic convolution model, a kind of matched filters in time - scale domain is designed for echo signal detection of ground penetrating radar ( gpr ) and implemented in this paper, which is applied to detect the location and amplitude of single reflection wavelet in receiving signal through continuous wavelet transform
摘要根據地震褶積模型，設計並實現了應用於探地雷達回波信號檢測的時間尺度域匹配濾波器，利用小波變換的時間定位性和尺度伸縮性，檢測出雷達接收信號中單個反射子波的位置與強弱信息，利用已知的雷達發射子波模型還原回波信號，達到了濾除噪聲、最佳接收的目的。
