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.   A direction of arrival estimation method for wideband LFM signals based on RWT and ESPRIT algorithm (EI收录) 会议论文 Advanced Materials Research, HongKong, China, August 21, 2014 - August 22, 2014 作者:  Xu, Jian-Zhong[1];  Yu, Fu-Qiang[2];  Duan, Ping-Guang[1];  Li, Shu-Hua[3] 收藏  |  浏览/下载：0/0  |  提交时间：2019/04/12 Algorithms  Chirp modulation  Frequency estimation  Frequency modulation  Mathematical transformations  Modulation  Radon
