Abstract

A fast spherical near-field to far-field transformation using single cuts is introduced in this paper. It is based on calculating the Cylindrical Modal Coefficients of each individual near-field ring and processing them independently, considering them as cylinders of zero height and applying probe correction. The reconstruction of each far-field cut is obtained through an inverse Fast Fourier Transform. This procedure provides the opportunity to perform real time transformations due to its low acquisition and processing time. It is a useful tool for applications which do not require a full or accurate characterization, such as measuring the main patterns of an antenna or its most important parameters (peak gain, beam width, side lobe level, etc.).
