摘要
Abstract
A method based on iterative FFT algorithm featuring an optimal peak side- lobe level i＇s presented, and the detailed steps of the method are discussed. This method can attack the problem of thinned planar array synthesis. The side-lobe level can be reduced when each iteration loop meeting the given peak side-lobe requirement starts with a different random initialization of element excitations by using the Fourier transform relationship exists between the array factor and the element excitations. Array thinning is accomplished by set- ting the amplitudes of the largest element excitations to unity and the others to zero during each iteration cycle. Finally,the simulated results confirming the great efficiency and the ro- bustness of the new method are shown in this paper.关键词
