摘　　要：针对相控阵雷达天线通道间存在幅度和相位误差,使得天线系统性能恶化的问题,该文采用一种相位交织算法实时提取一维相控阵雷达天线阵元幅度相位值,实现了天线性能在线监测和校正;并利用提取的阵元幅相信息形成方向图,根据波瓣统计特征,对天线性能进行评估。仿真和试验数据验证了该文方法是有效可行的。In view of the problem that amplitude and phase errors between antennae channels of the phased array radar make the antenna system performance deteriorated, the phase interleaving algorithm is used to extract amplitude and phase values for the one-dimensional antenna array of the phased-array radar and realize the on-line monitoring and correction on the antenna performance. The extracted element amplitude and phase information is used to form an antenna pattern and the antenna performance is given according to the statistical characteristics of the antenna pattern. The simulation and experimentation show that the proposed method is effective and feasible.
