A new methods is developed for extracting the Direction of Arrival (DOA) and estimating the power of several signals impinging on a linear array antenna with real valued genetic algorithm(GA). Good simulation results show the accuracy and reliability of the genetic algorithm, and it is one of effective methods to solve DOA estimation problems by using consolidation operator. Furthermore, without eigenvalue decomposition, computational complexity can be reduced.
