Linear independence of steering vectors of an electromagnetic vector sensor

  title={Linear independence of steering vectors of an electromagnetic vector sensor},

  journal={IEEE Trans. Signal Processing},
In this paper, we investigate linear independence of steering vectors of one electromagnetic vector sensor. We show that every three steering vectors with distinct directions of arrival (DOA’s) are linearly independent. We also show that four steering vectors with distinct DOA’s are linearly independent if the ellipticity angles of the signals associated with any two of the four steering vectors are distinct. Moreover, every four steering vectors corresponding to circularly polarized signals… CONTINUE READING
