| 摘 要： | 相控阵天线是隐身武器平台的重要散射源。该文通过相控阵天线散射模型对其模式项宽带散射特性进行仿真计算,并采用旋转目标散射中心成像方法对天线RCS仿真数据进行微波成像,研究了相控阵天线模式项散射的基本规律,并得到其散射中心分布图。仿真结果表明,相控阵天线斜置和天线端口阻抗匹配可大大减小威胁区域内模式项散射。研究结果对相控阵天线模式项RCS缩减工作具有良好的指导意义。

| Abstract: | Phased Array Antenna is an important EM Scattering source.on the stealth weapon platform.In this paper,phased array antenna mode scattering characteristics has been calculated.The RCS data has been used for microwave imaging by ISAR imaging method of rotating objects.General rules of phased array antenna scattering characteristics and scattering centers arrangement distribution chart have been studied.Tilting antenna and matched impedances can greatly reduce antenna mode RCS in the threaten area.The result is useful for phased array antenna mode RCS reduction. |
