Fig. 3From: A novel aliasing-free subband information fusion approach for wideband sparse spectral estimationThe 3D spectral-spatial spectrum of MUSIC with half-wavelength. The 3D spectral-spatial spectrum of MUSIC with two BPSK signals from −10° and 10° impinging on a ULA interspaced by half-wavelength relative to the highest frequency, SNR: 20 dB, K=256 and M=1Back to article page
