Sideband Suppression with Sub-sectional Optimized Time Steps in Time Modulated Linear Arrays

摘要：

　　This paper presents a novel approach to suppress sideband levels in time modulated linear arrays(TMLAs).The approach is based on the dividing of the time modulation period Tp into several subsections,and the switch-on and switch-off time in each subsection is optimized by the differential evolution(DE)algorithm.As compared to previous approach,the new approach has more flexibility and can be used to reduce sideband levels significantly.Numerical results of using the approach to suppress sideband levels in the case of uniform and non-uniform excitations are given.
