- W4311294763 abstract "The eigen-space MUSIC(ESMUSIC) algorithm based on spatial smoothing is a common method to estimate the signal direction of arrival (DOA). but in low signal to noise ratio (SNR),the ESMUSIC algorithm for estimating performance will reduce or even failure.Aiming at this problem, an improved spatial smoothing ESMUSIC algorithm (ISS-ESMUSIC) is proposed. First of all, the algorithm makes cross-correlated of all auto-correlation matrix of sub-array output,and then takes the spatial spectrum estimation to the equivalent spatial smoothing matrix after the forward and backward correlation matrices averaged. Finally, the ESMUSIC algorithm is used for the DOA estimation of targets. Simulation results show that the improvement of the algorithm can effectively estimate the DOA of coherent signals. And it performs better than classic MUSIC in the low SNR and low angle resolution." @default.
