A Multi-Beamspace High-Resolution DOA
Finding Algorithm for Wide-Band Sensor Arrays
Abstract:We propose a multi-beamspace Wide-Band(WB)digital beamforming system for the simultaneous
high-resolution Direction Of Arrival (DOA) detection of WB coherent and incoherent sources
clustered around separate regions each of which is scanned by a fixed number of WB beams. The
Coherent Signal Subspace algorithm is applied at the beamspace level for each set of beams
pointing to the same angle resulting in higher detection performance compared to a direct element-space
processing, sometimes with a lower computational cost as observed through some computer
simulation examples.
