A constrained optimization method to accomplish the amplitude quantizatoin of ultralow sidelobe phased array excitation is described.In this method, the 2 D separable multi step amplitude quantization and the correction of element mutual coupling of phased array synthesis are realized by means of introducing proper constrains into the optimization model. This method can be applied to other forms of phased array.Finally,some results are presented and discussed.
