Additive Deconvolution

Additive Deconvolution is a method applied to seismic traces for obtaining first join times of signals having predefined shape. Unlike the classic deconvolution the method does not involve the computing of reverse filter operator. A seismic trace is therefore considered as a sum of weighted signals of predefined shape and noise. To obtain the coefficients of joining impulses are used the Fourier transformation and the least-squares method.
