The results of numerical modeling the reconstruction of scalar and vector inhomogeneities are presented for purposes of acoustic tomography problems. In comparison with previously reported results, the joint reconstruction of sound speed, absorption coefficient, density and vector field of flows has been implemented. The considered acoustic tomography scheme is based on the two-dimensional functional-analytic Novikov-Agaltsov algorithm. The appropriate noise stability of this algorithm and its capability for the reconstruction of quite strong scatterers, which are beyond the first Born approximation, make it perspective to use the Novikov-Agaltsov algorithm for the development of practical schemes of acoustic tomography in different applications.
