A linear programming method has been used to design antenna array patterns that suppress interference from certain directions. The method is particularly useful since any degree of suppression can be specified. It is not necessary to impose exact nulls onto the pattern, although this can be done if desired. Moreover, by constraining real excitations to lie in the interval [‐1, 1], a pattern is obtained in which the majority of excitations remain at the quiescent value of unity. The method can be modified in principle to incorporate any other appropriate linear equality or inequality constraints on the pattern or the excitations. A detailed description of the method is given and several illustrative examples are included.
