【摘要】：提出了一种可控的宽带多功能反射屏.通过将射频微机电系统技术与反射屏设计相结合,首先设计了可编码式工作的单元,该单元具有工作频带宽、损耗小、控制简单的特点.由该单元基于不同编码矩阵构成的反射屏可以实现不同的功能.文中展示了多功能反射屏的极化旋转和捷变散射场性能.仿真结果表明:设计的反射屏在8.9—13.2 GHz频段范围内极化转化率高达90%以上,且在8.9—13.1 GHz频段范围内可实现10 d B以上的雷达散射截面减缩.实测结果与仿真结果基本一致.
[Abstract]:A controllable wideband multifunctional reflection screen is proposed. By combining the RF MEMS technology with the design of the reflective screen, a coding unit is designed, which has the advantages of low bandwidth, low loss and simple control. The reflection screen based on different coding matrices can achieve different functions. The polarization rotation and agile scattering field performance of the multifunctional reflector are shown in this paper. The simulation results show that the polarization conversion rate of the designed reflector is over 90% in the frequency range of 8.9-13.2 GHz, and the radar cross section can be reduced by more than 10 dB in the frequency range of 8.9-13.1 GHz. The measured results are in good agreement with the simulation results.
