摘要: 分析了直线和平面宽带相控阵天线扫描波束指向随工作频率改变而产生漂移的现象,给出了阵列单元或子阵采用实时延迟器后,这种指向漂移得以改善的估计。结果表明,漂移为原先的1/M(M为子阵列)。Abstract: In this paper,the excursion of beam-pointing versus frequency is analyzed while the linear or planar wideband phased array scanning.With realtime delayers are applied to array elements or subarrays,the excursion can be improved and the evaluation are given.It is shown that the improved excursion of beam-pointing is only about one Mth(M is the number of subarrays).
