Abstract
A nonstandard experimental and mathematical approach to the development of analytical and numerical multidimensional approximations for DGS diagrams is proposed. This method features sufficiently high accuracy, versatility, and reliability for different types of piezoelectric probes (PPs) and test objects (TOs). The efficiency of the approach is demonstrated by a test example and is also checked in its implementation in software for the UD4-S device based on standard specimens simulating flaws. Issues related to the solution of the direct and inverse problems of ultrasonic nondestructive testing are discussed.
