Modern signal and array processing methods now incorporate the physics of wave propagation as an integral part of the processing. Matched field processing (MFP) refers to signal and array processing techniques in which, rather than a plane wave arrival model, complex-valued (amplitude and phase) field predictions for propagating signals are used. Matched field processing has been successfully applied in ocean acoustics and electromagnetics. In this paper, source localization performance via MFP is examined in the electromagnetics domain. Specifically, the impact of uncertainty in the a priori knowledge of the underlying physical parameters, atmospheric refractivity vs. height, on source localization performance is examined
