Abstract :
The double-difference beam is a four-lobed far-field antenna response formed by an aperture illumination that has an antisymmetrical phase property in both dimensions of a planar antenna. Such a beam is useful for main beam ECCM applications. In this paper, we found that perturbing the roots of a Chesley double-difference pattern allows determination of a circular aperture distribution affording a double-difference pattern with side lobes of individually adjusted height.
