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论述了其分析方法和计算公式,给出了本文算法与作者(1993)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的计算比较结果。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。Abstract: A low sidelobe aperture designing method of multi-step amplitude quantization with pedestal is proposed, and general analysis and formulas are described. The computation results compared with author s(1993) previous method Multi-Step Amplitude 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.
