Beam pattern synthesis for line arrays subject to upper and lower constraining bounds

A technique is described for synthesizing the coefficients of an antenna array which satisfy a constrained minimax criterion. Inhibition regions can be formed in the beam pattern and placed advantageously in directions associated with strong sources of interference. Modified Dolph-Chebyshev beam patterns are obtained by imposing upper and lower constraining bounds on the beam pattern over regions of directions in space. Specific examples are presented for line arrays.
