Abstract
This paper evaluates interference suppression solutions using beamforming (BF) techniques based on phase control of the excitation signal for each element in the antenna array and metaheuristic algorithms. The metaheuristic algorithms investigated in this study include BA Algorithm (BA), Hybrid Particle Swarm Optimization-Gray Wolf Optimization (HPSOGWO), Multi-Verse Optimizer (MVO), and Jaya. Nulls are placed in the interfering directions on the radiation pattern of the equally spaced linear half-wavelength antenna array (Half-wave Dipole Uniformly spaced Linear Array-HDULA). The evaluation results have demonstrated that the interference suppression solutions based on metaheuristic algorithms are capable of suppressing sidelobes, maintaining the main lobe, and accurately imposing nulls in any interference direction. Furthermore, this evaluation has also shown that the solutions utilizing BA, HPSOGWO, and MVO outperform the Jaya-based ones in terms of computation time and null depth levels.
