摘　　要：考虑到成本和集成度等约束,传统的相控阵天线通常是单极化的或分时多极化的,并不对发射或接收信号时的极化形式进行精细调控,这会制约相控阵天线极化域效能的发挥。针对此问题,本文基于异构全极化相控阵,对其波束指向和极化参数进行联合调控,力图以较低的成本实现相控阵天线的全极化应用。首先,提出异构全极化相控阵的概念;然后,建立异构全极化相控阵的波束指向和极化参数联合调控数学模型;最后,提出联合调控方法并进行数学仿真。仿真结果证明了异构全极化相控阵的波束指向和极化参数联合调控方法的正确性和有效性。Considering cost and integration constraints,traditional phased array antennas are usually single-polarized or timemultiplexed polarized and do not finely regulate the polarization form when transmitting or receiving signals,which constrains the polarization domain efficiency of phased array antennas.To address this issue,this paper is based on heterogeneous fully polarized phased arrays and jointly regulate their beam pointing and polarization parameters,in an attempt to achieve the full polarization application of phased array antennas at a lower cost.Firstly,the concept of heterogeneous fully polarized phased arrays is proposed;then,the mathematical model for the joint regulation of beam pointing and polarization parameters of heterogeneous fully polarized phased arrays is established;finally,a joint regulation method is proposed and mathematically simulated.The simulation results demonstrate the correctness and effectiveness of the joint regulation method for beam pointing and polarization parameters of heterogeneous fully polarized phased arrays.
