摘要
应用遗传退火算法对32个数字阵列天线单元在64个位置进行了稀疏布阵,将单元间距和激励作为优化变量,在控制主瓣形状的同时,改善了阵列的副瓣电平,提供了更多的自由度来控制稀疏阵列的性能。结果表明,全局优化峰值旁瓣可低至-26dB,遗传退火算法能够避开遗传算法在搜索过程中的早熟收敛。
The Genetic annealing algorithm is proposed to synthesize the thinnned arrays with 32 units in the 64 positions. As the element spacings and excitation are used as variables to control the shape of the main lobe,it provides more degree of freedom to improve the sidelobe level. A - 26 dB peak side-lobe level is gained by the proposed algorithm which can avoid premature convergence of the search process.
