| 摘 要： | 减缩天线雷达散射截面时需要保证天线的基本辐射性能,这使得对其带内的雷达散射截面控制变得十分困难.为此,提出了加载不等长延时线的方法来实现阵列天线模式项雷达散射截面的减缩.由于天线模式项散射实质上是天线接收的入射能量经馈电内部不匹配处反射而从天线再次辐射所致,当给阵列单元与馈电网络之间接入一组延时线后,辐射能量只经过这组...

| Abstract: | The radiation performance of an antenna must be ensured when reducing the antenna radar cross section(RCS),which makes the in-band RCS difficult to control.For this reason,this paper presents the method of loading delay lines with a varying length to achieve the antenna-mode RCS reduction of an array antenna.Antenna-mode scattering is essentially the reradiation of reflected energy,which comes from the electromagnetic wave received by the antenna and reflects at the mismatched point of the feed network.When... |
