Digital processing of shallow seismic refraction data with the refraction convolution section / Цифровая обработка сейсмических данных преломления с использованием секции свертки преломления

In the last fifty years, there have been major advances in the acquisition, processing and interpretation of seismic reflection data. These advances have been driven largely by the spectacular developments in the electronic and computer industries.
The first was the common midpoint (CMP) method for acquiring data (Mayne, 1962). CMP methods improve the signal-to-noise (S/N) ratios of primary reflections through stacking redundant data.
The second was the application of signal processing with digital computers (Yilmaz, 1988). Digital processing achieves improvements in S/N ratios through the attenuation of coherent and random noise and some types of multiple energy, with CMP stacking and velocity filtering. It can also improve vertical resolution with deconvolution, and lateral resolution with migration or imaging. <...>
