An improved method for DOA estimation using one snapshot

The ability of decorrelation based on the mathematical model using one snapshot for DOA estimation is analyzed in the paper, and it is presented how to select the snapshot point. Then a new cumulation method is proposed using the periodicity of the transmitted signal. The proposed method can provide better DOA estimation performance at low SNR. The simulation results are presented, which indicate the proposed method is effective.
