Abstract—. The main aim of the study is to analyze the effect of the inhomogeneous medium to the inverse algorithm and compensation of the results via the inclusion of numerically obtained Green’s function of the propagation medium. Here,MUSIC based inverse algorithms are applied for the localization of objects in two-dimensional complex propagation region. The propagation medium is locally modeled using FDTD method. The scattered fields due to the object are obtained for multiple observation points in the required frequency band through two FDTD runs for each single source.
