Receiving Linear Array Beamforming Using Spatially Variant Apodization
DOI: 10.21293/1818-0442-2017-20-2-5-9
Abstract: The authors present a novel beamformer to receive linear array based on Spatially Variant Apodization. This technique reduces the side-lobe level compared with a uniform linear array, at the same time keeping the main lobe beam-width. For example, the side-lobe level of a 128-element linear array would be better than −30 dB in the presence of phase and amplitude errors based on the proposed technique (5.8 degrees r.m.s. and 0.5 dB r.m.s. respectively).
Keywords: linear antenna arrays, receiving antennas, adaptive filters, spatial filters
