Abstract

The invention discloses a rapid optimization design method and system based on a cylindrical surface conformal array, and belongs to the technical field of microwaves, and the method comprises the following steps: S1, setting modeling conditions; S2, selecting the number of optimization units; S3, optimizing the model by using an algorithm. According to the method, the cylinder array model is built by combining the periodic boundary condition and PML. The minimum number of units needed for optimization is found by utilizing the mutual coupling relation of the circumference of the cylinder, andthen optimization is carried out through algorithms such as heredity and the like. The cylinder array is modeled in a mode of combining the periodic boundary condition and the PML. The complexity ofthe model can be greatly reduced, the modeling efficiency is effectively improved. Mutual coupling strength relationship between the antenna units is utilized. The minimum number of units is selectedto optimize the central active standing wave. The time required by simulation can be greatly reduced, optimization design can be conveniently carried out on the antenna through algorithms such as heredity, and the method is worthy of being popularized and used.
