摘要： 提出了一种用于机载有源相控阵具有指数约束的二维可分离多阶振幅量化低副瓣口径设计技术，它能有效地降低水平面和非主平面的峰值副瓣电平并能减少Ｔ／Ｒ组件的品种数。采用二维可分离的设计思想，在工程应用中可大大地减少到馈网络的品种数。计算机仿真计算结果证明了理论分析。

Abstract: n this paper,a design technique of 2-D soparabl3 multi-step amplitude quantization low sidelobe apert ure distribution with exponent restraint for airborne solid-state active phased arrays is proposed. It i3 shod n that this method is' effective to reduce the peak sidelobe levels in horizontal plane and other areas and the kind of T/R modules. Using 2-D separable design idea, the number kinds of column feeding networks can be greatly reduced in engineering application. The. computer simulated results confirm the theoretical analysis.
