Fig. 6From: A novel aliasing-free subband information fusion approach for wideband sparse spectral estimationThe spatial spectra of two sources with 100 times half-wavelength. The spatial spectra of two BPSK signals from −10° and 10° on a ULA interspaced by 100 times half-wavelength relative to the highest frequency, SNR: 20 dB, K=256 and M=1Back to article page
