摘要
本文对二阶振幅量化密度加权的线阵和面阵天线进行了理论分析和模拟计算。结果表明,当具有相同的单元总数时,二阶密度加权阵的副瓣电平比一阶密度加权阵的副瓣电平低5到6分贝。本文把二阶密度加权推广到任意多阶的情况,给出了相应的理论分析和数值计算结果。
In this paper, the theoretical analysis and simulated computation of density weighted linear and planar arrays with two step amplitude quantization are presented. It is shown that when the total number of elements in the array remains constant, the peak sidel-obe level for the two step amplitude quantization array can gain 5-6 more dB reduction than that for the one step case. Finally, the generalized case for multi-step amplitude quantization is studied, and the relevant theoretical analysis and numerical results are given.
