| 摘 要： | 研究了降低机载雷达天线散射截面的频率选择表面(FSS)极化扭转板。根据Floquet定理利用模式电压概念建立矢量模式,对二维周期阵列的频率选择表面进行理论分析和计算。设计并加工了一种降低机载雷达天线散射载面的频率选择表面极化扭转板结构。计算和实验表明:频率选择表面的极化扭转板在雷达天线工作通带内保持与原极化扭转板的性能不变,而在工作通带外具有降低雷达散射载面的效果。降低雷达散射截面7～10dB。

| Abstract: | The frequency-polarization selective surface antenna to reduce radar cross section for airborne radar is investigated in this paper. Theoretical analysis and computation for two dimensional periodic structure FSS(Frequency Selective Surface) are established by vector mode methods on the basis of Floquet's theory, using mode voltage. Finally, an assembling structure of frequency-polarization selective surface is designed and manufactured to reduce radar cross section of airborne radar antenna. The numerical computation and experiment show that the characteristics inside the baseband of antenna have no change between FSS structure and primal polarization structure. FSS structure reduces radar cross section by 7- lOdB outside the baseband of antenna. |
