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. 关键词： Array signal processing, direction of arrival estimation, polarization, quad-quaternion. (浏览全文) 发表日期： 2008年04月03日 同行评议：
