Beschreibung
Zusammenfassung:	The main principles of spatiotemporal processing of signals during ultrasonic testing of articles manufactured from complexly structured materials with high signal attenuation are considered. Features of ultrasonic low-frequency testing limiting the application of the simplest algorithms for spatiotemporal signal processing in both ultrasonic flaw detection and ultrasonic tomography of articles manufactured from complexly structured materials are analyzed.
