Near-Field/Far-Field Transformation with Helicoidal Scanning from Irregularly Spaced Data

<table>Normalized maximum (■) and mean-square  (●) errors in the reconstruction of the NF data needed for the NF-FF transformation. Dotted lines: when using the nonuniform samples. Solid lines: when using the recovered helicoidal uniform samples.</table>
