| Summary: | Title screen The task of increasing the speed of defect image restoration is an urgent problem in the development of industrial ultrasound tomography based on digital coherent processing of matrix antenna array (AA) signals. In the context of this problem, the joint use of computationally efficient algorithms with calculations in the frequency domain and matrix AAs with nonequidistant arrangement of elements is considered within the framework of this paper. The joint application of these approaches to increase the speed of producing results is ensured through the use of a digital coherent processing algorithm based on the nonuniform fast Fourier transform (NUFFT). The effectiveness of this algorithm has been confirmed experimentally. Режим доступа: по договору с организацией-держателем ресурса |
