Abstract :
A new method of amplitude-phase distribution estimation for multielement antenna array is proposed after solving the optimization task and it is analyzed. It is based on main eigenvector calculation for spatial correlation matrix. Its application allows increasing the efficiency of both classic and “superresolution” methods of spatial tracking for priory unknown wideband signals.
