Abstract

Angle of arrival estimation using beam-space MUSIC is implemented by nonuniformly subbanding the spatial spectrum of an antenna array using wavelet transform. The resulting spatial spectrum is thus composed of beam-space elements with dyadically proportional beamwidths. Wavelet based spatial filtering is compared with that of the DFT in the context of direction of arrival estimation (DOA) performance. Issues of sidelobe level and mainlobe resolution are addressed.
