Direction of Arrival Estimation

Beamscan, MUSIC, MVDR, monopulse trackers, beamspace, ESPRIT, subspace methods

Use direction-of-arrival (DOA) estimation to localize the direction of a radiating or reflecting source. DOA algorithms include beamscan, minimum-variance distortionless response, MUSIC, 2-D MUSIC, and root-MUSIC. Monopulse trackers provide algorithms for tracking moving objects.
