| 摘 要： | 针对相控阵雷达扫描波位序列的编排问题，从天线波位的几何关系出发，提出了基于相交电平约束的最优扫描波位序列的编排算法以及最佳波住序列的性能评估指标，并在此基础上，重点分析了数字馈相对天线最优扫描波位序列的性能的影响。分析计算表明，在目前移相器位数很难做高的条件下，数字馈相将使最优扫描波位序列的性能严重恶化，在实际设计中必须对扫描波位序列进行优化设计。

| Abstract: | For phased array radar＇s optimal scanning beam position sequence scheduling problems, a scheduling algorithm for optimal scanning beam position based on intersection-level constraint as well as its performance evaluation indicators is put forward from the geometric relationship of antenna beam position. On this basis, the digital phasing＇s impact on the performance of the optimal beam position is mainly analyzed. Analysis shows that the performance of the optimal performance sequence is seriously deteriorated in the condition of limited phase shifter＇s control digit. Therefore the optimization of the scanning beam position sequence is a must in the actual design. |
