Abstract

The problem of flaw detection against a background of nonuniform structural noise is considered. The example of magnetic intratube flaw detection in seamless sections of trunk pipelines is analyzed. Synthesis of a two-dimensional optimal filter and application of the correlation method to a scaled model of a flaw are described. A comparative analysis of the application of this method to actual diagnostic signals is presented.
