摘要：

Null positioning and beam steering are the basic building blocks of Beamforming. Nulls in the radiation pattern of a radiating element are characterized by minimum radiation in the direction of its position. They suppress any radiation received in its direction. Some traditional numerical and computational intelligent heuristic techniques are proposed to position and steer nulls. In this paper simple Genetic Algorithm is used to position the nulls in the desired locations in the radiation pattern of a circular array. Nulls with predefined null depths are obtained with and without side lobe level (SLL) constraint. The convergence plots have shown the impact of the SLL constraint on the convergence.
