Figure 6

Comparison of RMSE of angle estimation of the proposed method, PAS method, and IPAS method versus SNR and snapshot number: (a) RMSE of uncorrelated angle estimation versus SNR with the fixed snapshot number 500; (b) RMSE of coherent angle estimation versus SNR with the fixed snapshot number 500; (c) RMSE of uncorrelated angle estimation versus snapshot number with the fixed SNR 20 dB; (d) RMSE of coherent angle estimation versus snapshot number with the fixed SNR 20 dB.
