Abstract
The paper introduces the use of Non-Uniform Fast Fourier Transform (NUFFT) routines in “complex” (i.e., amplitude and phase) and phaseless Near-Field/Far-Field transformations. The use of those routines results computationally very convenient when non-regular field sampling prevents the use of standard FFTs. The attention is focused on a plane-polar acquisition geometry. Numerical and experimental results show the effectiveness of the developed algorithmsKeywords
