摘要: 本文提出了一種帶平臺多階振幅量化的低副瓣口徑設(shè)計方法并論述了其分析方法和計算公式,給出了本文算法與作者(1993)提出的多階振幅量化方法在峰值副瓣電平、口徑效率、歸一化輸入功率以及具有容差情況下的副瓣惡化等的計算比較結(jié)果。結(jié)果表明,在相同的條件下,本文提出的方法優(yōu)于多階振幅量化方法。

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. -
