Abstract

The authors present a calibration technique for improving the accuracy of the near-field measurement with a 2D modulated scattering array. It is explained how the nonuniform characteristics in amplitude and in phase of a 2D array can be corrected by using a separate assessment of the array with a plane wave illumination. The calibration file is obtained by measuring a reference electric field provided by the ESTEC compact antenna test range. A comparison of a near-field measurement of a pyramidal horn is shown before and after such calibration.<>
