Figure 5From: ESPRIT with multiple-angle subarray beamformingAveraged ESPRIT-SB DOA RMSE versus (a) subarray number and (b) subarray separation for two equal-power signals from 55.6° and 56.1°, respectively. For (a), a fixed subarray spacing of five elements is used; (b), a fixed subarray number of four is used. The SNR is 5 dB and 50 snapshots are used.Back to article page
