基于遗传算法的部分比特自适应波束形成

Partial Bits Adaptive Beamforming Based on Genetic Algorithm

介绍了基于遗传算法的部分比特自适应波束形成方法，该方法可实现星载面天线阵方向图的实时综合。模拟实验结果表明，算法都能够在波束“凝视”方向满足指定增益的前提下对抗来自副瓣的强干扰。而且具有比唯相算法更快的收敛速度。本文的方法可用于任意平面阵列，其结果对工程和理论研究都具有重要意义。

An on board real time beam forming based on genetic algorithm is realized with plane array. A partially bits adaptive beamforming approach has been described and its performance has been analysed. The sim- ulations show that the algorithm can null the interferences coming from sidelobes, while the main lobe satisfy the gain and beam-pointing angle. And the algorithm offer the advantage of faster convergence rate over phase only algorithm. The method can be applied to arbitrary plane array which is very useful for engineering and theoretic analysis.
