DESIGN OF UNEQUALLY SPACED THINNED ARRAYS BASED ON GENETIC ALGORITHM AND SIMULATED ANNEALING
基于遗传算法和模拟退火的不等间距稀布阵的设计

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.
