The methods of restoration of amplitude-phase distribution in the antenna aperture by a transition to a plane wave on the basis of the asymptotic behavior of the Hankel functions at infinity and by direct calculation of the intensity of the components of the vector in a spherical coordinate system and transfer to a Cartesian plane on a uniform grid. Powered by comparing them to the data computing and natural experiments.
