Webused a residual median filter to dewow the data to preserve the causal nature of the wavelet (i.e., to avoid introducing precursors to the first arrivals) (Gerlitz et al., 1993). Careful processing is important to preserve the true arrival times in the data for later velocity analysis. RESULTS Webprocessed by applying a time-zero correction, dewow filter, linear gain, and high-pass filter over a 30-trace window. The GPR had a horizontal resolution of approximately 0.8 m, a sample rate of 0.05 ns, and an average trace spacing of approximately 0.15 m when pulled behind a snowmobile or approximately 0.07 m when towed by a skier or snowshoer.
WebIf a manual dewow correction is required, it is good practice to attempt a simple DC subtraction first, then either a median filter with a short filter … Webapplication of a dewow filter, and running average spatial filter, followed by a diffraction stack migration and a bandpass filter. Figure 2 represents the before and after processing display of Line X7. A velocity value of 0.072 m/ns, measured interactively in the field by curve fitting, was used in migration.

WebAug 1, 2024 · The dewow time filter was first applied to each radargram to remove of the initial DC component and low-frequency, slowly decaying ‘wow’, while preserving the high frequency signal [76]. These can be produced by several factors, but are primarily the result of early wave arrivals, dynamic range limitations on instrumentation, and/or ...
