The problem of rapid far-field computation from near-field samples acquired on a plane-polar geometry is addressed in this paper. A fast processing algorithm is developed which uses the fast Fourier transform and the related shift theorem, by exploiting the convolution property of the radiation integral giving the antenna far-field pattern. Numerical and experimental examples are discussed to prove the effectiveness of the proposed procedure.

Abstract
The problem of rapid far-field computation from near-field samples acquired on a plane-polar geometry is addressed in this paper. A fast processing algorithm is developed which uses the fast Fourier transform and the related shift theorem, by exploiting the convolution property of the radiation integral giving the antenna far-field pattern. Numerical and experimental examples are discussed to prove the effectiveness of the proposed procedure.File in questo prodotto:
