A new DOA estimation algorithm based on differential spectrum
Y.R. Ferreira, Rodrigo Pinto Lemos · 2006
This work proposes a new DOA estimation algorithm based upon the difference between the singu- lar values of the estimated spatial covariance matrix. The proposed method presented competitive RMSE performance when compared to MODEX and Root-MUSIC. Specifically for low SNR values, near angles and correlated signals, this new method had a better performed. Index Terms— DOA estimation, Array signal processing, Adaptive arrays.
