摘　　要：为研究相控阵雷达常规回扫方式受移相器位数的限制而引起的杂波抑制性能变化的问题,首先分析了相控阵雷达不同工作模式对动目标显示(MTI)改善因子的影响;然后对机械转动回扫补偿探测模式进行了优化,分析了移相器位数不同对杂波抑制带来的影响.仿真结果与理论分析相符,对雷达的相关工作模式设计有指导意义.The conventional back-sweep mode of phased array radar is limited by the phase shifters’digit,which results in the variation of clutter suppression performance.In order to study the above issue,this paper first analyzes the influence of different operating modes of phased array radar on the improvement factor of moving target indication(MTI),then optimizes the compensation detection mode of mechanical rotation scan retrace,and finally analyzes the influence of different digit of phase shifters on clutter suppression.The simulation results are in agreement with the theoretical analysis and have a guiding significance for the design of radar’s relevant working mode.
