We investigate the inverse problems of acoustics and electrodynamics. We apply wave and diffusion additional information for inverse problem solution [1]. The inverse problem for wave equation (wave approximation), inverse problem for diffusion equation (diffusion approximation) and inverse problem with combined data of wave and diffusion. Such problems arise in electroacoustic tomography [4] and GPR studies [3, 5]. We analyse the ill-posednes of the inverse problem by singular value decomposition [2]. It was shown that the involvement of data from different physical processes makes it possible to improve the stability of the inverse problem.
