The present disclosure provides a method for generate array element excitation of a conformal array based on an iterative algorithm, the method comprises obtaining a first index of a pattern of an array antenna by a processor; obtaining multiple optimization objectives according to design indexes of the array antenna by the processor; based on the first index, iteratively determining, by the processor, a first array element excitation satisfying a dynamic range ratio (DRR) of an array element excitation amplitude under the first index through a preset conversion relationship and a preset approach; based on the first array element excitation, obtaining, by the processor, a second array element excitation satisfying the multiple optimization objectives under a constraint of the DRR of the array element excitation amplitude through a solution algorithm; based on the second array element excitation, the design indexes, and basic parameters, generating, by the processor, the array antenna, the basic parameters including the number of array elements, a working center frequency, and an array element spacing of the array antenna.
