Abstract :
The space-frequency-polarization (SFP) beam-former using an electromagnetic vector sensor was studied in this paper. An improved robust beamformer algorithm was put forward which was based on Capon and joint constraint. As the three domains joint information was used, the SFP beamformer substantially outperforms any two-domain joint beamformer. Finally, Simulation results verified the effectiveness of the SFP beamformer and the SFP robust beamformer.
