About Applicability of Antenna Array Technology for Ultrasonic Inspection of Hazardous Production Facilities

V. A. Voronkov, I. V. Voronkov, V. N. Kozlov, A. A. Samokrutov, V. G. Shevaldykin

Operating principles of ultrasonic flaw detectors with antenna arrays are considered: the principle of physical generation of electronic-driven ultrasound beam – for devices with phased arrays, and the principle of spatio-temporal processing of signals independently obtained from each couple of array elements – for devices with digitally focused array’s aperture.
The principles are compared on the criteria of possibility and practical availability of pre-test flaw detector sensitivity adjustment for reliable detection and regulatory rejecting detected discontinuities.
