ANGLE ESTIMATION USING A POLARIZATION SENSITIVE ARRAY

In a previous paper, the authors described how the ESPRIT algorithm may be used to estimate both the arrival directions and the polarizations Of incoming plane waves with a uniform linear array of crossed dipoles. An alternative approach is described here that may be used with the same array to estimate arrival angles only. This new approach has the advantage that it requires far fewer computations. The performance of this approach is compared with that of the original approach and with that of estimators using conventional ESPRIT arrays.
