Abstract :
A genetic algorithm has been used for null steering in phased and adaptive arrays. It is shown that it is possible to steer the array nulls precisely to the required interference directions and to achieve any prescribed null depths. The use of genetic algorithm removes the restrictions on the array element displacements, required in the case of linear analytic method. Results are obtained for axial, elevational and arbitrary directional element positional perturbations through genetic algorithm for imposing nulls in the desired directions in the radiation pattern
