In this paper, a numerical pattern synthesis algorithm for an array is presented in the basis of the adaptive array theory. By employing the iteration technique, the algorithm can find a set of optimum weights that steer the main beam in a given direction and yield the sidelobes meeting a specified level. Its advantage is suitable to an arbitrary set of array elements, and the array can have arbitrary nonuniform spacing between elements. The numerical results indicate that the algorithm is effective.
