Quad-Quaternion MUSIC for DOA Estimation Using Electromagnetic Vector Sensors

Quad-Quaternion MUSIC for DOA Estimation Using Electromagnetic Vector Sensors

A new quad-quaternion model is herein established for an electromagnetic vector-sensor array, under which a multidimensional algebra-based direction-of-arrival (DOA) estimation algorithm, termed as quad-quaternion MUSIC (QQ-MUSIC), is proposed. This method provides DOA estimation (decoupled from pol...
