【摘要】 本文针对大角度扫描设计了一款X波段共形相控阵天线,采用了先优化单元间间距,组成紧凑型的平面阵列,然后利用两面共形技术进一步扩大扫描角度的综合方法。仿真结果表明此共形天线阵列工作在X波段,具有57度的较广扫描范围,并同时满足副瓣电平低于-10dB和波瓣宽度不大于21度。该设计对雷达相控阵大角度扫描研究有着重要的意义。更多还原

【Abstract】 This paper design one conformal phased array antenna based on the demands of X band and wide scanning angle. In order to expand the scanning range, a method combining optimizing element spacing and adopting the conformal technology of2-faceted surface is used in this paper. The simulation results show that the conformal antenna array works in x-band, and has wide scanning range of 57 degrees. At the same time, its sidelobe level is less than-10 dB and its lobe width is not more than 21 degrees. The design has important significance to phased array radar.更多还原
