  In this paper, a fast algorithm for the Direction Of Arrival (DOA) estimation
of radiating sources, based on partial covariance matrix and without eigende-
composition of incoming signals is extended to two dimensional problem of joint
azimuth and elevation estimation angles using Uniform Circular Array (UCA) in
case of non coherent narrowband signals. Simulation results are presented with
both Additive White Gaussian Noise (AWGN) and real symmetric Toeplitz noise.
