摘要
本文提出了一种用于机载有源阵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列馈网络的品种数。
In this paper, a designing technique of 2- D separable multi-step amplitude quantization low sidelobe aperture distribution with exponent restraint for airborne solid -state active phased arrays is proposed. It is shown that this method is effective in reducing the peak sidelobe levels in horizatical plane and other areas as well as the variety of T/R modules. Starting from the 2 - D scparable design idea,the variety of column feeding network can be greatly reduced in engineering application. The computer simulated results agree well with th from the theoretical analysis.
