Improved Harris hawks algorithm for pattern shaping of linear antenna arrays
In order to better solve the problem about side lobe level suppression and nulls control of linear antenna arrays,an improved Harris hawks algorithm(IHHA)is proposed.The algorithm first uses a single eagle search strategy to expand the global search scope of the algorithm,and then introduces adaptive control theory to improve the search accuracy of the algorithm and ac-celerate the convergence of the algorithm.The simulation results show that compared with particle swarm optimization,cuckoo search algorithm,ant colony optimization algorithm and standard Harris hawks optimization algorithm,the proposed algorithm has more advantages in reducing the side lobe level and controlling nulls of the linear antenna arrays.
