Wideband DOA estimation using a frequency-domain frequency-invariant beamformer and a matrix pencil method

초록

We describe an extension of the wideband direction-of-arrival (DOA) estimation method using a frequency-domain frequency-invariant beamformer (FDFIB). The technique uses the Matrix Pencil Method (MPM) instead of conventional methods based on the eigenstructure of the input covariance matrix. MPM offers excellent resolution compared to conventional methods.
