陣列天線的遺傳優(yōu)化
OPTIMIZATION OF ARRAYS BY GENETIC ALGORITHM

摘要: 非均勻稀布陣通常具有較高的旁瓣。為降低旁瓣,本文對傳統(tǒng)遺傳算法進行了改進并用于陣元位置的優(yōu)化。對于一個孔徑為50,由25個陣元組成的陣列天線,本文獲得了比已有文獻更低的旁瓣。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
