Abstract :
Beamspace root-MUSIC is a computationally efficient, beamspace implementation of root-MUSIC developed recently for use in conjunction with a uniformly spaced linear array. Using B real-valued beams having all but B-1 nulls in common, the major computations in beamspace root-MUSIC are a B×B real-valued eigenvalue decomposition and the rooting of a polynomial of order either 2B-2 or B-1. Beamspace root-MUSIC is extended for other common array geometries including the rectangular array, the circular array, and the minimum redundancy linear array
