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