An Optimum Method of Linear Thinned Array Based on Iterative FFT Algorithm

An optimum method based on iterative FFT featuring a low peak sidelobe level of linear thinned array is presented. The initial excitation generation method and the judgment criterion of the optimal result in each single iteration cycle are improved, these improvements reduce the search space of the algorithm and reduce the probability of unsatisfactory results, the detail steps of the method are shown in this paper. The calculate results prove the efficiency and stability of proposed method.
