Polarized smart antenna array has attracted considerable interest due to its capacity of matched reception or interference suppression for active sensing systems. Existing literature does not take full advantage of the combination of polarization isolation and smart antennas and only focuses on uniform linear array (ULA). In this paper, an innovative synthesis two-dimensional beampattern method with a null that has cross-polarization for polarized planar arrays is proposed in the first stage. This method aims to further enhance the capability of interference suppression whose optimization problem can be solved by second-order conic programming. In the second stage, a new sparse array-optimized method for the polarized antenna array is proposed to reduce the high cost caused by the planar array that is composed of polarized dipole antennas. Numerical examples are provided to demonstrate the advantages of the proposed approach over state-of-the-art methods.

极化智能天线阵列的二维波束方向图综合及其稀疏阵列优化

极化智能天线阵列由于其匹配的接收或有源感应系统的干扰抑制能力而备受关注。现有文献没有充分利用极化隔离和智能天线的组合，而仅关注均匀线性阵列（ULA）。本文在第一阶段提出了一种创新的具有零位的合成二维束图方法，该方法对偏振平面阵列具有交叉极化。该方法旨在进一步增强干扰抑制能力，其干扰问题可以通过二次圆锥编程解决。在第二阶段，提出了一种新的针对极化天线阵列的稀疏阵列优化方法，以减少由极化偶极天线组成的平面阵列引起的高成本。
