We present an innovative Near-Field test range, named Compact Near-Field (CNF) test range, using photonic probes and advanced Near-Field Far-Field transformations (NFFF). The photonic probe allows distances of one wavelength or less between AUT and probe, drastically reducing test range and scanner dimensions, improving the Signal to Clutter Ratio and the Signal to Noise Ratio, and reducing the scanning area and time. The NFFF, properly formulated as a linear inverse problem, further improves the rejection to clutter, noise and truncation error. The advantages of CNF test ranges are numerically foreseen and experimental results are presented under both, planar and cylindrical scanning geometries.

Abstract
We present an innovative Near-Field test range, named Compact Near-Field (CNF) test range, using photonic probes and advanced Near-Field Far-Field transformations (NFFF). The photonic probe allows distances of one wavelength or less between AUT and probe, drastically reducing test range and scanner dimensions, improving the Signal to Clutter Ratio and the Signal to Noise Ratio, and reducing the scanning area and time. The NFFF, properly formulated as a linear inverse problem, further improves the rejection to clutter, noise and truncation error. The advantages of CNF test ranges are numerically foreseen and experimental results are presented under both, planar and cylindrical scanning geometries.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
