	DOA estimation algorithm of UWB signal based on unitary circuit array (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者: Zhang X.; Chen X.; Chen X.; Chen X.; Zhang X. 收藏 \| 浏览/下载：32/0 \| 提交时间：2013/03/25 In this contribution unitary circular array (UCA) techniques for estimating Direction of Arrival (DOA) of Ultra wideband (UWB) propagation signals are studied. 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.
