Research on localization of emitter source in forest environment using inverse diffraction parabolic equation based on finite difference method

Abstract

The localization of non-cooperative emitter sources is a hot and difficult problem in the modern war. The arithmetic of Inverse Diffraction Parabolic Equation has a good applicability and stability characteristic for passive localization in complex environment. In this paper, an inverse diffraction parabolic equation model based on finite difference method (FDM) is constructed to research the localization of the emitter source over forested environment. The article introduces a handing method of forest vegetation and analyzes the effects of forest vegetation on accuracy of transmitter positioning. Simulation results proved that the Inverse Algorithm of Finite Difference Parabolic Equation does a good localization estimate of the emitter source.
