摘　　要：共形阵列天线中信源方位、极化和互耦系数相互耦合,已有经典阵列的互耦误差校正算法均不能有效地移植应用。针对柱面共形载体的单曲率特点,通过合理的天线布局,利用互耦矩阵的Toeplitz性和秩损理论,给出了柱面共形阵列天线互耦条件下信源方位与极化的联合估计算法,并对可能出现的方位角模糊进行了详细的分析,给出解模糊方法。所提算法无需参数配对,即可实现信源方位、极化和互耦系数的联合估计。计算机Monte-Carlo仿真实验验证了该算法的有效性。The azimuth,polarization and mutual coupling parameters are coupled with each other in cylindrical conformal array antenna.The existing mutual coupling calibrations in classical linear and planar arrays can’t be applied here.According to the single curvature characteristic of cylindrical conformal carrier,sensors are arranged appropriately here,at the same time,the Rank Loss theory and the characteristic of Toeplitz matrices are utilized,just because of these above,a new joint estimation algorithm for azimuth,polarization and array mutual coupling parameters is introduced in this paper.In this algorithm,the possible problem about the azimuth ambiguity could be analyzed in detail and solved accordingly.The azimuth,polarization and mutual coupling parameters joint estimation are acquired jointly without the need for parameter matching.The estimation algorithm is validated by Monte-Carlo simulation on computer.
