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.   Picosecond ultra-wideband short pulse radiated by antenna arrays 期刊论文  OAI收割 microwave and optical technology letters, 2007, 卷号: 49, 期号: 5, 页码: 1148-1151 作者:  Ruan, Chi;  Zhao, Wei;  Chen, Guo-Fu;  Zhu, Shao-Lan;  Liu, Bai-Yu 收藏  |  浏览/下载：74/11  |  提交时间：2010/01/12 ultra-wideband short pulse  antenna array  electromagnetic pulse  coherent
