Fig. 8From: DOA estimation algorithm based on spread spectrum sequence in low signal-to-noise ratioOverestimation (underestimation) probability at different SNR (x axis: Signal-to-noise ratio form − 30 dB ~10 dB; y axis: Probability of Overestimation (underestimation)). Overestimation: The estimated number of sources is more than the actual number of sources. Underestimation: The estimated number of sources is less than the actual number of sourcesBack to article page
