In this paper, the Hybrid Grey Wolf and Improved Bat Optimization Algorithm (HWIBO) is proposed to reduce the peak sidelobe level (PSLL) of linear symmetric array synthesis with aperture and element spacing constraints.The HWIBO utilizes both the Grey Wolf Optimization (GWO) and Improved Bat Algorithms (IBA) simultaneously to optimize PSLL.Each iteration generates two sets of results, and the optimal result is chosen for the next loop.Compared to other algorithms used in simulation of antenna sidelobe suppression, the HWIBO not only inherits the fast convergence advantage of the IBA which enhances population diversity but also possesses the strong global search capability of the GWO.This helps the IBA escape local optima and strengthens the global search capability during the later stages of algorithm iterations.Finally, the simulation results demonstrate the successful reduction of PSLL under various constraints, confirming the effectiveness of the hybrid algorithm.
