WebIn this letter, a novel window for improving the resolution of the images is proposed. This window uses a modified Ricker wavelet function to minimize the power leakage factor, main lobe width, and increase relative sidelobe attenuation (rSLA). Furthermore, a generalized equation based on a modified Ricker wavelet function is proposed whose parameters … WebRicker wavelets (fig 1) are zero-phase wavelets with a central peak and two smaller side lobes. A Ricker wavelet can be uniquely specified with only a single parameter," f ", it's peak frequency as seen on the wavelet's …
Time Frequency Analysis of Wavelet and Fourier Transform
WebThere are 20 shots and 280 receivers distributed on the top of the ore-hosting velocity model. The recording time is 3.2 s, with a 2 ms time interval. To better match the filed datasets, in this case, a low-cut 6 Hz Ricker wavelet with a dominant frequency of 15 Hz is used to test the ability of low-frequency dependence . In addition, we ...

Why Ricker Wavelets Are Successful In Processing Seismic …
WebABSTRACT The 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 frequency-domain bandwidth of the Ricker wavelet and … Webscipy.signal.ricker — Scipy function for a Ricker wavelet, which takes a scale parameter a = 1/2πf (I think) Mexican hat wavelet — Wikipedia article; Ryan, 1994. A choice of wavelets. … WebJul 14, 2024 · When considering this filter applied to a Ricker wavelet, we establish an analytical expression of the peak-frequency attribute as a function of propagation and reflection properties. mangieris in south austin
