The commonly used stable factor methods for the inverse [Formula: see text]-filter achieve good performance in seismic data processing; however, constant gain-limit assumption these is not associated with effective frequency band of and cannot obtain desirable results high resolution signal-to-noise ratio (S/N). Our extended method extends by introducing two parameters or self-adaptive gain limit to high-resolution high-S/N result. can be implemented time-frequency domain; latter...
Synchrosqueezing transform (SST) has been used to address the problems in many diverse disciplines. However, calculated instantaneous frequency (CIF) precision by SST decreases with increase time-sample interval and actual frequency. This will lead an incorrect time-frequency distribution. To eliminate impact of enhance CIF resolution, we propose adaptive time-resampled high-resolution SST, which spectrum for calculation is adapted highest its effective band desired precision. A synthetic...
Abstract The Hilbert transform (HT) has been widely used in seismic data processing and interpretation. However, HT results exhibit lower noise robustness resolution. This paper extends by introducing three orders greater than or equal to 0 the sign function frequency domain propose an extended (EHT) which many advantages over HT—particularly robustness, resolution, a variety of applications. output EHT depends on choice function.

Wavefield separation is one critical step in the three-component (3C) vertical seismic profiling (VSP) data processing. The conventional 3C VSP wavefield method exhibits low precision polarization angle and cannot obtain desirable results. This letter proposed right-hand rule which has many advantages over method-particularly wavefields continuity. Analysis of real demonstrates that can enhance show a very ability to produce high-continuity wavefields.
