| 摘 要： | 基于交叉偶极子构成的锥面共形阵列,建立了四元数表示的锥面共形阵列模型并提出了四元数多重信号分类 (multiple signal classification,MUSIC)算法。算法通过同极化子阵的构造以及秩损原理实现了导向矢量中极化信息和波达方向(direction of arrival,DOA)信息的剥离,进而得到入射信号的二维DOA估计和极化参数估计,有效降低了极化DOA联合估计的计算量。仿真结果验证了算法的有效性。

| Abstract: | Based on conical conformal array with crossed dipole elements, the quaternion array signal model is built, and the quaternion multiple signal classification (MUSIC) algorithm is proposed. This algorithm realizes de-coupling polarization and direction of arrival (DOA) information through resetting the elements with the same polarizations of sub-arrays and the principle of rank-loss, then it obtains the estimations of 2D DOA and the polarization parameter of incident signals. The computational complexity of joint polarization-DOA estimation is reduced significantly. Finally, the simulation result verifies the effectiveness of the method. |
