【摘要】 相控阵天线以其自身的诸多优点,已经成为雷达与卫星的主要天线形式。为使相控阵天线散射场主瓣偏离来波方向,倾斜安装已经成为隐身相控阵雷达的主流安装方式。此时,副瓣成为倾斜安装的相控阵天线雷达散射截面(Radar Cross Section,RCS)的主要贡献者。同时,对于辐射场,低副瓣也决定了相控阵天线抗干扰和抗杂波能力。因此相控阵天线辐射场和散射场的副瓣控制技术成为高性能隐身相控阵天线设计的研究重点。为此,本文结合遗传算法(Genetic Algorithm,GA)优化确定相控阵天线的天线单元排布形式,同时实现相控阵天线辐射场和散射场的低副瓣。更多还原

【Abstract】 Phased array antenna with its own advantages has become the main antenna of radar and satellite system.In order to make the main lobe deviate from the oncoming waves,the inclined installation has become mainstream installation of stealth phased array radar.At this time,the side-lobe becomes the main radar cross section contributor of inclined phased array antenna.Meanwhile,for the radiation field,low side-lobe also determines the clutter and anti-jamming capability of phased array antenna.Therefore,phased array antenna radiation and scattering side-lobe control technology become research focus of high-performance and stealth phased array antenna.In this paper,combined with Genetic Algorithm optimization to determine the form of antenna elements arrangement of phased array antenna,to achieve radiation and scattering low side-lobe.更多还原
