摘要
利用不同长度、不同增益的介质天线构成稀布阵列。针对有阵列孔径、阵元数目、最小间距约束的稀布阵列综合问题,采用线性候选机制的果蝇算法(LGMS-FOA)。以改善峰值副瓣电平为目标函数,对阵元分布位置以及介质棒长度进行快速优化,同时实现扫描角在±15°内较好的扫描特性。
Sparse array consists of dielectric antenna with different gains and different length.Under the constraints of fixing the aperture,the number of elements and the minimum element spacing of the sparse array,a linear generation mechanism of candidate solution based on fruit fly algorithm(LGMS-FOA)was adopted.To reduce the peak side-lobe level,the position of elements and the length of dielectric rod antenna are optimized and good scanning ability of antenna also realized in the range of±15°angles.
