We develop a high-resolution method for estimating the directions-of-arrival of partially polarised signals with electromagnetic (EM) vector sensors, of which each provides measurements of the complete electric and magnetic fields induced by EM signals. The method is computationally efficient since unlike many high-resolution methods, it does not involve searching across a multi-dimensional array manifold. In addition, it does not require a priori information about the array system such as sensor positions.
