Аннотация:Numerical implementation of the two-dimensional functional-analytical Novikov–Agaltsov algorithm is considered and its possibilities are discussed. This algorithm is intended for reconstructing combined scalar-vector inhomogeneities describing spatial distributions of the speed of sound, absorption, and vector flow field. The results of the numerical simulation of the algorithm in the single- and multifrequency probing modes are presented. The obtained results illustrate an acceptable accuracy and interference resistance of the obtained estimates, which illustrates the application prospects of the algorithm in practical problems of acoustic tomography.
