摘要
In this paper, a synthesis method for a shaped-beam pattern of the 2-D array antenna is proposed. The method is based on the array scanning principle and the superposition principle. The method can limit the ripple of the main beam by adjusting the sampling point interval and can easily achieve low sidelobe level (SLL). Compared to the stochastic optimization methods, this method has obvious time advantage when it is used to synthesize a large array antenna. The factors that affect the SLL, ripple, and dynamic range ratio (DRR) are discussed. Sparse array is used to reduce DRR.
