| 摘 要： | 本文采用一种新的基于遗传算法的天线阵列的自适应算法。根据实际的硬件限制,不改变阵列的幅度加权,而通过遗传算法对相位加权作全局优化。为减小对天线方向图的破坏,并希望在干扰源来波方向实时置零,因而采用只优化搜索数字移相器的最后几位。计算机模拟结果证实了这种方法的有效性。

| Abstract: | In this paper, a new approach based on genetic algorithm (GA) is applied to adaptive array, in according to the limitation of hardware, the amplitude weights are not changed, but the phase weights are optimized globally with genetic algorithm. For reducing the perturbations to the far field pattern and placing multiple deep nulls real-time in the directions of interference, a genetic algorithm adjusts some of the least significant bits of the beam steering phase shifters. Simulation results confirm the theoretical work. |
