Abstract :
Calibration at the array level as well as the development of specific algorithms for direction finding and accurate polarimetric estimation are presented for a circular array of eight connected wideband 3D Taper Slot Antennas (TSA). A straight relation is established between the number of spherical modes used to describe the embedded element patterns and the precision on the angle of arrival and polarization estimation.
