%X 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.
