| 摘 要： | 雷达天线是飞机的强散射源之一,对飞机整机RCS的贡献是显而易见的。雷达天线是特殊的散射体,其散射机理比普通散射体更为复杂。相控阵天线在低散射特性方面具有先天优势,对相控阵天线的结构项散射、模式项散射、RCS栅瓣3大强散射源进行了研究,分别对其散射机理进行了分析,并提出了相应的缩减方法,为低RCS相控阵天线的设计提供了依据。采用低RCS综合设计的相控阵天线其散射可以降低10 dB～20 dB,获得很低的RCS散射特性。

| Abstract: | Radar antenna is the major contributor of battleplan scattering,which has great influence on the RCS of battleplan.Phased array antennas scattering is really made up of several contributors.The three major contributors are antenna-structural scattering,antenna-mode scattering and RCS grating lobes.The three major contributor of scattering is studied,the scattering principle is analyzed,and the reduction of which are also presented.If the phased array antennas adopt low RCS design,RCS can be reduced 10 dB～20 dB. |
