Ricker wavelet 地震
WebApr 12, 2024 · The time step of source wavelet is 0.05 μ s, and the calculation time is 40 μ s. We use the same Ricker wavelet in two numerical simulations, as illustrated in Figure 4 (a). The spectrum of the source wavelet is shown in Figure 4 (b). The peak frequency is 0.5 MHz and the -3 dB bandwidth range is about 0.27MHz to 0.8MHz. Web小波在奇异性信号的检测上具有独特的优势,在图像边缘检测、网络异常检测、地震异常与语音异常识别等领域有着广泛地应用[1-5]。 然而用不同的小波处理相同的信号数据序列有着不同的处理结果,为了取得更好的处理结果, Mallat[6]针对图像边缘提取发明了 ...

WebBut the same rule applies the other way: convolution in the frequency domain is equivalent to multiplication in the time domain. S (f)=W (f)*R (f) => s (t)=w (t).r (t) In order to get a wavelet (in time) whose Fourier transform is a Gaussian centered at a certain frequency, you will need to multiply a sinusoid of that certain frequency by a ... WebThe Ricker wavelet is theoretically a solution of the Stokes differential equation, which takes into account the effect of Newtonian viscosity, and is applicable to seismic waves propagated through viscoelastic homogeneous media. In this paper, we defined the time-domain breadth and the
In mathematics and numerical analysis, the Ricker wavelet is the negative normalized second derivative of a Gaussian function, i.e., up to scale and normalization, the second Hermite function. It is a special case of the family of continuous wavelets (wavelets used in a continuous wavelet transform) known as Hermitian wavelets. The Ricker wavelet is frequently employed to mo… WebOct 1, 2015 · INTRODUCTION. The Ricker wavelet is a well-known symmetrical waveform in the time domain (Ricker 1953 ).

WebThe functions x0(t) proposed by Ricker are therefore known as Ricker wavelets. The power spectrum S(!) of a Ricker wavelet x0(t) has the form S(!) = K ! 2 exp(c !); where c = ˙2 and K is a constant. 1.3 Ricker wavelets have been empirically successful Since the original Ricker’s paper, Ricker wavelets have been successfully used in processing
