摘要
本文提出了一种带平台多阶振幅量化的低副瓣口径设计方法，并对这种方法进行了理论分析，推出了计算公式，给出了本文所述算法与我们以前提出的“多阶振幅量化方法”在峰值副瓣电平、口径效率、归一化输入功率以及具有容差情况下的副瓣恶化等方面的比较计算结果。结果表明：在相同的条件下，本文提出的方法优于“多阶振幅量化方法”。
A low sidelobe aperture design method of multi-step amplitude quantization with pedestal is proposed.and general analysis and formulas are described. The computation results compared with our previous method“Multi-Step Ampli-tude Quantization(MSAQ)”on peak sidelobe level,aperture efficiency,normalized input power and sidelobe degradation with tolerance are given. It is shown that,in the same conditions,the method presented in this paper is better than the MSAQ.
