Abstract

Spiral phased array antenna nulling is presented. The array factor and classic method for spiral array antenna proposed here. Proposed method and genetic algorithm for optimization of fixed nulling in spiral array antenna are used and compared. The goal is to achieve a -20 dB in null over the wide frequency band. Our simulation shows -20 dB over 75 MHz null bandwidth, in VHF band by GA and over 90 MHz null bandwidth by proposed design method.

提出了一种利用螺旋阵列天线进行宽带消零的方法

介绍了螺旋相控阵天线的消零。本文提出了螺旋阵列天线的阵列因子和经典方法。将该方法与遗传算法用于螺旋阵列天线固定零点优化，并进行了比较。目标是在宽频带内实现-20 dB的零值。仿真结果表明，采用遗传算法在VHF频段的75 MHz以上零带宽为-20 dB，采用所提出的设计方法在90 MHz以上零带宽为-20 dB。
