摘　　要：介绍了宽带相控阵天线孔径渡越时间延时补偿原理,提出了一种分布式宽带大角度扫描相控阵天线阵面波束控制技术,该技术采用孔径渡越时间分级延时算法和高精度通道相位误差补偿。通过仿真和实测数据,证明了该技术可有效改善宽带相控阵雷达色散效应,得到性能与系统复杂度之间的平衡,并基于分布式分层求解波束运算控制系统实现了工程化应用。In order to solve the technology problems brought by aperture fill time in the applications of wideband phased array ra-dar,a distributed antenna beam steering technique is proposed,which is suited for large sweeping angle phased array.By leveled compensation with high precision,the error of real-time and phase is compensated well.The technique could deduce the dispersion and be a good trade-off between the performance and complexity of the phased array.The technique is fully engineered and tested by the related simulations and experiments.
