基于四元数的极化敏感阵列波束形成
Adaptive Beamforming Based on Quaternion for Polarization Sensitive Array
摘要
Abstract
Quaternion signal model can keep the intrinsical orthogonality of the polarization sensitive ar-ray(PSA),so the processing method based on quaternion outperforms the performance of traditional long vector method based on complexor for PSA.The quaternion optimal weight vector is obtained through the maximum signal interference noise ratio criterion and it is used to complete the filtering of PSA in this paper. The quaternion method can achieve the same filtering performance as the long vector method.Also,the com-putational burden is reduced and only a half of the memory space is required.At the same time,four dimen-sional orthogonal structures of quaternion can enhance the robustness when there exists array pointing errors. Simulation results are given to demonstrate the effectiveness of the proposed method.关键词
