摘要
应用实数编码的遗传算法进行阵列天线方向图综合的优化设计。针对阵列天线方向图综合的特点,运用算法,通过优化单元电流幅度、阵元间距,对阵列天线方向图进行了综合优化,其中包括方向图的波瓣控制和零点生成,并同时压低旁瓣电平使其达到期望值。仿真结果表明,通过优化,天线阵的辐射特性获得很大的改善,在主瓣宽度满足要求的情况下,副瓣电平也可达到-33.6100dB。良好的仿真结果表明遗传算法在阵列天线方向图综合中的应用是有效的,有良好的应用前景。
A real coded genetic algorithm is applied to synthesize the array antenna pattern. The maximum relative sidelobe level of antenna arrary is optimized by controlling the amplitude, element positions based on genetic algorithm. It includes controlling the width of mainlobe level. Good results show that the genetic algorithm is an effective method for solving such problems and the sidelobe level can reach - 33. 6100dB ,the characteristic of antenna arrary radition pattern is improved. Pattern synthesis of antenna array is actualized successfully using this approach. Genetic algorithm shows its good application potentials,
