Adaptive circular antenna arrays with beam-steering are very important components of space navigation, and radar systems. A problem may occur when the receiver is jammed by an interference signal, and a quick reaction is required in this regard. An immediate solution to this problem is to have an adaptive fast beamforming algorithm that suppresses the interference signal by steering the radiation pattern nulls in the same direction of the interference signal. A novel technique is proposed here that incorporates genetic algorithm and Schelkunoff nulling theory to achieve fast steering of the main beam and nulls in the desired directions. The proposed computational process allows the genetic algorithm to perform the beam steering and null placement within a considerably reduced processing time compared to the standard optimization technique. The proposed algorithm is employed successfully without compromising all other radiation pattern characteristics.

自适应圆形天线阵列中的快速波束转向和零点定位

具有波束控制功能的自适应圆形天线阵列是空间导航和雷达系统的重要组成部分。当接收器被干扰信号干扰时可能会出现问题，对此需要快速反应。该问题的直接解决方案是采用自适应快速波束成形算法，该算法通过在干扰信号的相同方向上控制辐射方向图的零点来抑制干扰信号。这里提出了一种新技术，该技术结合了遗传算法和 Schelkunoff 归零理论，以实现主波束的快速转向和所需方向的归零。与标准优化技术相比，所提出的计算过程允许遗传算法在显着减少的处理时间内执行波束转向和零位放置。
