DOA Estimation with Spatial Spread Vector-Sensor Array Based on Biquaternion MUSIC

DOA Estimation with Spatial Spread Vector-Sensor Array Based on Biquaternion MUSIC

The mutual coupling among various components of the collocated crossdipole (CCD) vector-sensor is severe, and its application is greatly limited. The spatial spread dipole (SSD) vector-sensor can avoid this problem, but the multiple signal classification (MUSIC) algorithm for the SSD array is rarely...
