The synthesized video-signal method in nondestructive-testing problems

A method based on a proposed echolocation diagnostic technique (RF Patent 2446407 dated 27.03.2012) can be efficient for detecting both single and multiple defects with a sufficiently high accuracy, is described with a view to the development of diagnostic equipment. The essence of the method is the...

Zusammenfassung:	A method based on a proposed echolocation diagnostic technique (RF Patent 2446407 dated 27.03.2012) can be efficient for detecting both single and multiple defects with a sufficiently high accuracy, is described with a view to the development of diagnostic equipment. The essence of the method is the use of a probing signal composed by sequentially formed harmonic oscillations at several different frequencies, and a joint processing of received reflected signals.
