Aiming at the defects of the DOA algorithms under uniform linear array (ULA) only can estimate 180 degree unfaintness angles  in this paper  the algorithms of one-dimensional and two-dimensional DOA estimation for UWB signals based on unitary circular array (UCA) are proposed. In order to estimate DS-UWB signals within 360 degree angles  the UCA-CSM-RB-MUSIC algorithm is proposed  which can estimate 360 degree unfaintness azimuth angles. 2010 IEEE.
