Direction finding/polarization estimation - Dipole and/or loop triad(s)

This paper shows 1) how measurement of the three Cartesian components of the electrical-field or magnetic-field suffices for multisource azimuth/elevation direction finding and polarization estimation, and 2) how the vector cross-product direction of-arrival estimator is fully applicable even when the dipole triad is arbitrarily displaced from the loop triad.
