For ultrasonic inspection of austenitic materials, two antenna arrays (Dual Matrix Array (DML)) are often used, operating in a separate combined mode. Special prisms have been developed to work with DMA. The use of DMA makes it possible to increase the signal-to-noise ratio of the image of reflectors, reduce the level of reverberation noise, which allows using prisms with a reduced arrow, and focusing the field in three-dimensional space.
To equalize spatial sensitivity, it is proposed to use the inverse CFA method, which takes into account not only the delay times of the arrival of echo signals, but also the distortion of their amplitude and phase due to refraction and reflection at the boundary of the control object. This approach makes it possible, without special sensitivity equalization procedures, to restore images of lateral cylindrical holes so that the amplitudes of their indications vary within ± 2 dB in the operating range of antenna array angles.
