The article concerns the experimental validation of two techniques for compensating the probe positioning errors in a near-field–far-field transformation with cylindrical scan using a nonredundant number of measurements.The former uses the singular value decomposition method and can be applied when the irregularly acquired samples lie on nonuniform rings, thus allowing to reduce the starting two-dimensional problem into two independent one-dimensional ones. The latter, based on an iterative technique, can be employed also when the previous hypothesis does not hold but requires the existence of a one-to-one correspondence, associating at each uniform sampling point the nearest irregular one.

Abstract

The article concerns the experimental validation of two techniques for compensating the probe positioning errors in a near-field–far-field transformation with cylindrical scan using a nonredundant number of measurements.The former uses the singular value decomposition method and can be applied when the irregularly acquired samples lie on nonuniform rings, thus allowing to reduce the starting two-dimensional problem into two independent one-dimensional ones. The latter, based on an iterative technique, can be employed also when the previous hypothesis does not hold but requires the existence of a one-to-one correspondence, associating at each uniform sampling point the nearest irregular one.
