DOA estimation of coherent resources based on matrix reconstruction

Abstract

This study presents a direction-of-arrival (DOA) estimation method for coherent signals. DOA estimation is an important part in the target precision locating. But, when the signals are correlated, conventional algorithm will fail in DOA estimation such as MUSIC. A new de-correlation DOA estimation algorithm is proposed for this. It is based on the cross-correlation vector matrix reconstruction. For wide coherent signals, its performance is superior to ISM and CSM. Simulation results are presented to illustrate the efficiency and accuracy of this method. © 2014 Springer-Verlag.
