Antenna Integration in Near-Field Backscattering Model based on IPO and EEC

This article proposes a model to incorporate antenna effects within a scattering model in the close proximity to the target. The approach is based on an efficient Iterative Physical Optic (IPO) and Equivalent Edge Current (EEC) model, that iteratively computes the electric and magnetic currents on the surfaces and edges composing the target. Unlike the classical plane wave incidence, the incoming fields are originate from the antenna, and their effects are taken into account. The scattered fields are then received by the antenna according to their direction of arrival and polarization. The approach is presented for two different canonical antennas, and the round-trip channel transfer function in monostatic and bistatic scenarios, is evaluated and benchmarked with full wave simulations.
