Beamspace Root-MUSIC is a computationally cfficicnt, beamspace implementation of Root-MUSIC developed recently for use in conjunction with a uniform linear array (ULA). Employing B real-valued beams having all but B-l nulls in common, the major computations in Beamspace Root-MUSIC are a BxB real-valued eigenvalue decomposition (EVD) and the rooting of a polynomial of order B-l. Recently, Beamspace Root-MUSIC was adapted for use in conjunction with a uniform circular array (UCA) employing the interpolated array concept of Friedlander. We here develop an alternative means of using Beamspace Root-MUSIC with a UCA based on the concept of phase mode excitation.
