N2 - By exploiting information about the spatial derivative of magnitude data, we increase the reliability of phaseless near-field far-field transformations. While existing techniques operate on the measured magnitudes, the presented formulation puts restrictions on the first-order spatial derivative of the measured magnitudes. This potentially allows to utilize 'hidden' information about the antenna near fields and, thus, increase the chances of a successful phaseless transformation. Preliminary simulation results for an implementation based on the fully-analytic equations for the spatial derivatives of the magnitude of fields caused by Hertzian dipoles are presented. The comparison as well as combination with a typical phaseless solver not using the spatial derivatives showcases the potential of the new formulation.
