| 摘 要： | 副瓣电平在天线阵列的设计中是很重要的指标,已经有很多方法进行这方面的改进。该文在稀布阵概念的基础上,引入了距离微扰,提出不等间距稀布阵的模型,来进一步改善天线阵的副瓣电平,并且利用遗传算法和模拟退火对这种不等间距稀布阵进行了综合设计。给出了200元线阵和40×20面阵的优化结果,从仿真结果可以看到天线副瓣电平得到了改善。

| Abstract: | The sidelobe level is an important factor in designing of antenna arrays, and several methods have been developed to improve it. A model of unequally spaced thinned array is given in this paper, which introduces a distance perturbation into the element of a thinned array, in order to improve the sidelobe level. Genetic algorithm and simulated annealing are used to design this kind of array. The pattern of a 200 elements linear array and a 40×20 planar array is presented for the isotropic element pattern, the results verifies the improvement of the sidelobe level. |
