2-D DOA tracking using variational sparse Bayesian learning embedded with Kalman filter
EURASIP Journal on Advances in Signal Processing, 2018 In this paper, we consider the 2-D direction-of-arrival (DOA) tracking problem. The signals are captured by a uniform spherical array and therefore can be analyzed in the spherical harmonics domain.
