| Research Abstract |
In this research, we tried to apply Genetic Algorithm, Immune Algorithm andParticle Swarm Optimization to high resolution direction of arrival estimation.When the incident wave in the near field sources becomes a spherical wave, the complex calculation is needed with theMUSIC method though the incident wave was assumed to be a plane wave in conventional ways ofDOA estimation.As results of simulations, we confirmed the accuracy of direction of arrival estimation with metaheuristics and have shown its effectiveness.
