EXPERIMENTAL VALIDATION OF A NEW TECHNIQUE TO REDUCE THE TRUNCATION ERROR IN NEAR-FIELD FAR-FIELD MEASUREMENT TECHNIQUE

摘要

The technique is based on a non-redundant and non uniform representation of the near-field on the measurement plane and performs an estimation of the fields samples outside the measurement region. Thanks to the non uniformly distribution of the samples, also the estimation of a limited number of them allows a significant improvement in the far field reconstruction. The numerical and experimental investigation presented in this paper confirms the effectiveness and flexibility of the technique, which requires a low computational effort.
