The optimal difference pattern of the line array can be accurately solved. The classical algorithm utilizes the characteristics of the Zolotarev polynomial and adopts a method such as Dolph-Chebyshev synthesis optimization and direction map. However, the implementation of this algorithm is very difficult. In this paper, we propose a new synthesis method by using the characteristics of the optimal difference graph. The new method is a numerical iteration algorithm, we will show through examples that it can achieve the required accuracy of the project. The new algorithm has the advantages of simple implementation and flexible application.
