Quad-quaternion MUSIC for DOA Estimation
全部作者： 龔曉峰 徐友根 劉志文 第1作者單位： 北京理工大學信息科學技術學院摘要： A new quad-quaternion model is herein established for a six-component electro-magnetic vector-sensor array, under which a multidimensional-algebra based direc-tion-of-arrival (DOA) estimation algorithm, termed as quad-quaternion MUSIC (QQ-MUSIC), is proposed. This method provides DOA estimation (decoupled from polarization) by exploiting the orthogonality of the newly defined ‘quad-quaternion’ signal and noise subspaces. Due to the stronger constraints that quad-quaternion or-thogonality imposes on quad-quaternion vectors, QQ-MUSIC is shown to offer great robustness to model errors, and thus is very competent in practice. Simulation results have validated the proposed method. 關鍵詞： Array signal processing, direction of arrival estimation, polarization, quad-quaternion. (瀏覽全文) 發表日期： 2008年04月03日 同行評議：
