摘　　要：针对电子侦察装备往高灵敏度、高精度和一体化方向发展需求,提出一种极化可重构阵列的信号多域测量方法.通过四个高增益极化可重构天线子阵列构建四天线阵元多基线相位干涉仪,满足雷达信号和通信信号的最优极化接收和高灵敏度侦测,完成信号极化域、频域、时域和空域等多域特征参数的测量;根据来波信号极化方向,选择对应极化幅相一致性误差数据校正补偿,实现高精度测向.仿真结果验证了该方法的可行性.For the development requirements of electronic reconnaissance equipment in the direction of high sensitivity,high precision and integration,this paper proposes a signal multi-domain measurement method of polarization reconfigurable array.First,a four-antenna array element multi-baseline phase interferometer is constructed by four high-gain polarization reconfigurable antenna subarrays to meet the optimal polarization reception and high sensitivity detection of radar signals and communication signals,and complete the measurement of multi-domain characteristic parameters such as signal polarization domain,frequency domain,time domain and space domain,etc.Then,according to the polarization direction of the incoming wave signal,the corresponding polarization amplitude-phase consistency error data is selected for correction and compensation to achieve high-precision direction finding.Simulation results verify the feasibility of the proposed method.
