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. © 2006 Wiley Periodicals, Inc.
