Abstract : Three effective numerical approaches to a novel inverse problem in wave propagation and diffusion are presented. Given partial information concerning the solution of the telegrapher's equation, various coefficient in the equation are determined using Laplace transforms, semidiscretization, and finite difference methods. Fields of application are radio-wave propagation, automatic control, and oceanography, where it is desired to determine the physical properties of an inhomogeneous medium based on observations of the response of the medium to an input signal.
