摘要: 本文論述了一種多階振幅量化二維固態(tài)有源相控陣天線獲得低副瓣的口徑設(shè)計方法,這種方法可適用于任意復(fù)雜口徑天線。另外,對于由隨機(jī)幅相誤差和單元(或T/R組件)失效而引起的副瓣電平惡化和增益下降也進(jìn)行了分析。

Abstract: An aperture design technique using multi-step amplitude quantization for two-dimensional solid-state active phased arrays to achieve low sidelobe is described. It can be applied to antennas with the arbitrary complex aperture. Also, the gain drop and the sidelobe degradation due to random amplitude and phase errors and element (or T/R module) failures are investigated. -
