The paper is devoted to automated analysis of defectograms at rail inspection using software-hardware system “ASTRA”. A general structure of analysis algorithms is given. Approaches to a filtration of digital signals from mobile flaw detectors "Echo-complex 1" and "Echo-complex 2" are described. The approaches allow noise filtering, minimizing false flaws amount and saving useful inclined coherent bundles of signals from defects and structural elements of rails and railroad switches.
