This paper proposes a new adaptive hybrid filter scheme based on the least mean square and the recursive least square algorithms for uniform linear antenna arrays to generate radiation beam patterns. The individual adaptive blocks used to form the new filter are interconnected by the linear array factor to simulate a virtual antenna array and to set the desired direction of the main beam pattern. The completed formulation of the new filter is detailed and its capability to minimize interference signals and adaptive white gaussian noise is evaluated by simulation and compared with other filters. The simulation results showed that the convergence speed and the filtering characteristics of the new model are better or similar to those that make it. In conclusion, the new scheme can generate the main beam pattern to the desired signal direction.
