固态有源相控阵天线多阶振幅量化及副瓣特性的研究

Study of Multi-Step Quantization and Sidelobe Characteristic for Solid-State Active Phased Arrays

本文研究了多阶振幅量化二维低副瓣固态有源相控阵天线的口径设计方法，结果表明，这种方法能够有效地降低固态有源相控阵的峰值副瓣电平，并且可适用于任意复杂口径天线．另外，对于随机幅相误差和单元（或Ｔ／Ｒ组件）失效而引起的增益损失及峰值副瓣电平恶化也进行了分析。

In this paper,an aperture designing technique of multi-step amplitude quantization for twodimensional solid-state active phased arrays to transmit low sidelobe is described.It is shown that this method is effective to reduce the peak sidelobe level of solid-state active phased arrays and can be applied to the arbitrary complex aperture antennas.In addition,gain loss and sidelobe degradation due to random amplitude and phase errors and element(or T/R module) failure are investigated.
