Abstract
In 2011 acoustic researches laboratory first proposed the sparse approximation method for detailed inner structure analysis of the geoacoustic emission signals measured continuously in Kamchatka. This paper considers the use of combined dictionaries for signal sparse approximation. The improved matching pursuit algorithm of refinement in the parameter space is proposed.
