Stochastic framework for evaluating the effect of displaced antenna elements on DOA estimation [PDF]

open access: yes, 2017
We establish a statistical framework for investigating the influence of correlated random displacements of antenna elements in a uniform circular antenna array (UCA) on the distribution of direction-of-arrival (DOA) estimates. More specifically, we apply
