Abstract

A method for reducing the side lobe level (SLL) of the combination factor (CF) of a linear equidistant phased array antenna (LEPAA) in a given direction within the framework of the model problem with given partial diagrams is presented. We obtained analytical dependences of the amplitude distribution (AD) and phase distribution (PD) of the signal at the inputs of the LEPAA emitters on the angles in the direction to which the minima of the LEPAA CF are formed. An example of SLL suppression is considered. We investigated the dependence of the SLL CF LEPAA on the bit capacity of the power amplifiers and phase shifters in the LEPAA channels. It is shown that an LEPAA CF SLLs of –100 dB is achieved with account for the bit capacity of the power amplifiers and phase shifters in a given direction with 16-bit sampling, and an LEPAA CF SLLs of –200 dB is achieved with 32-bit sampling.

具有给定部分图的天线阵列辐射模型问题中旁瓣电平的抑制

摘要

提出了一种在给定部分图的模型问题框架内，在给定方向上降低线性等距相控阵天线 (LEPAA) 组合因子 (CF) 旁瓣电平 (SLL) 的方法。我们获得了 LEPAA 发射器输入处信号的幅度分布 (AD) 和相位分布 (PD) 与形成 LEPAA CF 最小值的方向上的角度的分析相关性。考虑了 SLL 抑制的一个例子。我们研究了 SLL CF LEPAA 对 LEPAA 通道中功率放大器和移相器比特容量的依赖性。结果表明，考虑到功率放大器和移相器在 16 位采样的给定方向上的位容量，可实现 –100 dB 的 LEPAA CF SLL，
