Abstract

This work proposes a new DOA estimation algorithm based upon the difference between the singular values of the estimated spatial covariance matrix. The proposed method presented competitive RMSE performance when compared to MODEX and Root-MUSIC. Specifically under low SNR values, for near angles and correlated signals, the new method performed better.
