The EMC118X family employs frequency-hopping on the sampling frequency, which avoids the injection of coherent noise and enables traces of up to 8 inches while maintaining accurate temperature readings.
Receiver arrays are used to attenuate undesired coherent noise in certain wave numbers.
In recent years, Halliday D (2011) has used an adaptive interferometry method for ground-roll suppression and Henley D (2003) has tried to attenuate coherent noise in the radial trace domain.
Thresholding is well behaved for seismic random noise attenuation but causes trouble for data-processors for coherent noise attenuation.
It can be quickly applied to a large volume of data and coherent noise in seismic data was successfully attenuated with this type of discrete wavelet transform.
She had lost the ability to make a coherent noise, the treatment proceeded against her will and contrary to her best wishes.
This unique module can identify not only coherent noise sources, but also multiple incoherent and partially coherent noise sources.
It is characterized by low velocity and frequency and high amplitude, being considered a coherent noise in seismic exploration (D'Agosto et al.
The shot gather in Figure 5, was generated using dynamite, it displays hyperbolic moveout, coherent noise masking the reflection signals.
Land seismic data is commonly contaminated with strong coherent noise such as multiples, ground-roll, converted waves, etc.
Because coherent noise is generated by a specific, well-known physical mechanism, it is possible to model if an accurate subsurface model in terms of velocity and density is available.
