Abstract : It is proved that the minimum phase-only weight perturbations required to impose a single null in a real, linear array, antenna pattern are odd-symmetric with respect to a phase reference at the center of the array. Hence the perturbed pattern is likewise real. Additional evidence is given for supporting the hypothesis that the minimum phase-only weight perturbations are odd-symmetric for any number of imposed nulls. (Author)
