提出了一种基于双四元数的非圆源测向算法。阵列输出的协方差和共轭协方差矩阵在双四元数框架内被对称地利用。在双四元数域中，找到与噪声子空间正交的双四元数导向向量的到达方向。仿真结果表明，该方法与其他复杂方法相比，性能有所提高。
A biquaternion-based direction-finding algorithm for noncircular sources is presented. The covariance and conjugate covariance matrices of the array output are utilized symmetrically within a frame of biquaternions. The direction-of-arrivals are found where the biquaternion steering vectors are orthogonal to the noise subspace in the biquaternion domain. Simulations show the improved performance of the proposed method compared to its complex counterparts.
