Abstract—This paper deals with different beamforming
techniques for DOA estimation. High resolution techniques
such as Multiple Signal Classification (MUSIC) and Estimation
of Signal Parameters via Rotational Invariance Techniques
(ESPRIT) which are subspace based techniques are also
discussed. Finally, further resolution improvement is achieved
through the use of directional sensors. The computational
complexities of beamforming techniques are also compared.
Index Terms—Beamforming, computations,
direction-of-arrival, multiple, radar, resolution.
