Averaged ESPRIT-SB DOA RMSE versus (a) subarray number and (b) subarray separation for three equal-power signals from 25.6°, 26.3°, and 27.0°, 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.
