摘要：

The time modulation technique is utilized for the synthesis of power patterns in linear arrays. The differential evolution algorithm is employed both to shape the beam requirements and to suppress the sideband patterns. Numerical results show that the time-modulated linear array can be successfully used to synthesize power patterns and the excitation dynamic-range ratio can be reduced significantly as compared to those of the conventional arrays.
