Anti-aliasing Condition and Filter for Reciprocity Equations of Correlation Type
نویسندگان
چکیده
An anti-aliasing formula is derived for interferometric redatuming of seismic data. More generally, this formula is valid for numerical implementation of the reciprocity equations of correlation type, which is used for redatuming, extrapolation, interpolation, and migration. The anti-aliasing condition can be, surprisingly, more tolerant of a coarser trace sampling compared to the standard anti-aliasing condition. Numerical results with synthetic data show that interferometry artifacts are effectively reduced when the anti-aliasing condition is applied to interferometric redatuming.

Multi-rate receivers with IF sampling and digital timing correction
This contribution deals with the design of a fully digital multi-rate receiver, operating on non-synchronized bandpass samples. Issues related to aliasing, sample rate conversion and timing correction are considered. We compare various receiver alternatives in terms of the BER degradation caused by aliasing and non-ideal timing correction. In particular, we focus on a low-complexity receiver pe...
متن کاملSampling conditions for anisotropic diffusion
Multi-resolution image analysis utilizes subsampled image representations for applications such as image coding, hierarchical image segmentation and fast image smoothing. An anti-aliasing filter may be used to insure that the sampled signals adequately represent the frequency components/features of the higher resolution signal. Sampling theories associated with linear anti-aliasing filtering ar...
متن کاملInformation Loss and Anti-Aliasing Filters in Multirate Systems
This work investigates the information loss in a decimation system, i.e., in a downsampler preceded by an antialiasing filter. It is shown that, without a specific signal model in mind, the anti-aliasing filter cannot reduce information loss, while, e.g., for a simple signal-plus-noise model it can. For the Gaussian case, the optimal anti-aliasing filter is shown to coincide with the one obtain...
متن کاملReverse Time Migration = Generalized Diffraction Stack Migration
The standard reverse-time migration (RTM) algorithm is usually described as zero-lag correlation of the backprojected data with the source wavefield. The data are back-projected by a finite-difference algorithm, where each trace acts as a source-time history of a point source at the geophone location. This is a simple and easily understood migration method, but appears inflexible to improvement...
متن کاملTutorial: Basics of choosing and designing the best filter for an effective data-acquisition system
One of the jobs of a circuit designer is to build a measurement system that provides valid input-to-output data as defined by the system requirements over a given frequency range. The four possible elements of a signal path include a gain/signal conditioning cell, an anti-aliasing filter, an analog-to-digital converter (ADC) and a digital processing block. Figure 1 shows this type of system wit...
