Abstract :
A novel algorithm is presented to estimate 2-D nominal angles of multiple coherently distributed sources in a uniform circular array (UCA). Based on a decoupled generalised array response vector and single centro-symmetric UCA, the proposed algorithm can estimate the nominal angles without any information about the deterministic angular distribution functions of the sources or additional array structures.
