Based on the quaternion formulation of Maxwell equations
a pure biquaternion model (PB-MODEL) for electromagnetic vector-sensor array is proposed.Theoretical analysis shows that the pure biquaternion data covariance matrix can decorrelate the coherent noise among the electric or magnetic antennas of a vector-sensor.As a result
the corresponding pure biquaternion multiple signals classification algorithm (PB-MUSIC) can be extended to coherent noise cases. Numerical simulation verifies the correctness of our algorithm and the analytical results.
