Abstract: A genetic algorithm assisted beam tracking and forming is applied to solve the problem of tracking a continuous moving signal while suppressing a strong fixed interference. An improved binary coding method is proposed, which introduces several parameters to control the solution precision and search space efficiently. The convergence and reliability of this algorithm are given much consideration. The simulation results show that the algorithm is able to track a fast moving signal while suppressing a fixed interference.
