阵列天线的遗传优化
OPTIMIZATION OF ARRAYS BY GENETIC ALGORITHM

摘要: 非均匀稀布阵通常具有较高的旁瓣。为降低旁瓣,本文对传统遗传算法进行了改进并用于阵元位置的优化。对于一个孔径为50,由25个阵元组成的阵列天线,本文获得了比已有文献更低的旁瓣。

Abstract: Unequally spaced arrays are characterized by high side lobes. To reduce the side lobes, traditional genetic algorithm is modified to optimize the position of elements in the array. Due to the high flexibility of genetic algorithm, the results obtained for a 25-element array over an aperture of 50 are better than those reported in the literatures -
