摘　　要：相控阵雷达必须具有大瞬时带宽才能满足雷达多功能的要求,本文从大瞬时带宽相控阵天线设计原理出发,研究了瞬时带宽与指向精度对延时器校准的影响机理。在保证大瞬时带宽内波束色散以及波束指向精度要求下,提出1种大瞬时带宽相控阵天线时延校准的方法。最后,结合仿真验证了本方法可大大降低标校工作量的良好结果。Large Instantaneous bandwidth of phased array radar can be adapted to the multifunctional development requirement.Based on the design principle of phased array antenna with large Instantaneous bandwidth,the influence mechanism of instantaneous bandwidth and pointing accuracy on calibration is studied in this paper.In order to ensure the beam dispersion and pointing accuracy in large Instantaneous bandwidth,a calibrated method of the time delay for phased array antenna of large aperture and instantaneous bandwidth is proposed.Finally,the simulation results prove that the method can greatly reduce the workload of calibration.
