Abstract
This letter proposes an elegant 1-D search technique to compute 2-D DOA estimation using the MUSIC algorithm for the case of a single source. Unlike a conventional planar array configuration for 2-D DOA estimation, this letter involves a linear array with alternate elements orthogonally polarized. The validity of the proposed analysis has been established through specific cases of array elements being rectangular waveguide and circular waveguide. Very good agreement of results between the estimated DOA involving the conventional 2-D search and proposed 1-D search substantiates the validity of the proposed technique. The computation time for the proposed DOA technique is reduced by a factor of 50 and 150 for 1 ° and 0.5 ° search intervals, respectively, when compared with the conventional 2-D MUSIC algorithm.
