Sammanfattning

In this paper, a generic electromagnetic model is utilized for arbitrary multiport antennas e.g., vector sensors applied in DOA estimation, which was exploited for the statistical analysis of DOA and polarization estimation. By utilizing the spherical vector wave expansion of the electromagnetic field to completely characterize the multiport antennas a general framework for modelling an antenna configuration based on measurements or computations including e.g., mutual coupling is obtained. The array manifold can easily be expanded over a dense spatial grid to enable high-resolution DOA estimation without demanding further measurements of the antenna characteristics.
