本文论述了一种多阶振幅量化二维固态有源相控阵天线获得低副瓣的口径设计方法,这种方法可适用于任意复杂口径天线。另外,对于由随机幅相误差和单元(或T/R组件)失效而引起的副瓣电平恶化和增益下降也进行了分析。
In this paper, a method of aperture design for obtaining low sidelobes of multi-order amplitude-quantized two-dimensional solid-state active phased array antenna is presented. This method can be applied to any complex aperture antenna. In addition, sidelobe level deterioration and gain reduction due to random amplitude and phase errors and unit (or T / R) failure are also analyzed.
