Abstract
This paper discusses the deployment of Genetic algorithm optimization method for synthesis of antenna array radiation pattern in adaptive beamforming. The synthesis problem discussed is to find the weights of the antenna array elements that are optimum to provide the radiation pattern with maximum reduction in the sidelobe level A continuous GA with a population size 10 and a mutation rate of 0.35 with Roulette selection is run for a total of 500 generations using MATLAB and the best result was found for each iteration. This technique proved its effectiveness in improving the performance of the antenna array.
