| 摘 要： | 针对柱面共形阵列天线的单曲率特点,建立了柱面共形阵列天线的快拍数据模型,基于高分辨波迭方向(DOA)估计的子空间原理与秩损理论,结合合理的阵元排列结构设计,将信源极化状态、俯仰角以及方位角去耦合,通过参数的一维搜索与方程求解,实现了信源极化状态未知条件下的2D DOA估计.针对相干信源情况,推导了柱面共形阵列天线的解相...

| Abstract: | In view of the single curvature of cylindrical conformal array antenna,the array output data model for cylindrical conformal array is established.Based on rank-reduction estimator(RARE),subspace principle and well-designed configuration of elements on cylindrical carriers,the decoupling method for elevation,azimuth angles and polarization parameters of sources is implemented,and the 2D direction of arrival(DOA) is estimated by means of one-dimensional search and solution of equations without the exact knowl... |
