From: DOA estimation algorithm based on spread spectrum sequence in low signal-to-noise ratio
The detection probability of the proposed method and the CSM method under different SNRs. The figure compares the performance of the proposed source estimation algorithm and the CSM method (x axis: Signal-to-noise ratio form \(-30\) dB ~10 dB; y axis: Probability of successful detection). CSM: coherent signal subspace method. Proposed: MUSIC algorithm based on spread spectrum sequence
