摘要：

In this study, a novel method is proposed to obtain the minimum elements and a specific sidelobe in time-modulated sparse linear arrays. A genetic algorithm is used to optimise each generation of arrays to reach the required level and range of the sidelobe. Furthermore, the number, arrangement, and switching sequences of the array that satisfy the requirements are obtained. This method provides a scheme to reduce the number of elements using the optimised sparse structure and switching time. However, besides the control of the fundamental component, this method can also be applied to multi-beam forming with the fundamental component and +/- first harmonic. Finally, the effectiveness of the proposed method is verified by the simulation and numerical results.
