Abstract
In this article, the application of phaseless measurement in spherical nearfield antenna measurements is discussed, where the amplitude is measured and used to estimate the Spherical Mode Coefficients (SMC) of the antenna. Implementing phaseless measurement in a spherical nearfield setting is challenging, since the spherical nearfield data and its SMC depend highly on the structure of the spherical harmonics or Wigner Dfunctions, which can be seen as the Fourier basis on the sphere and rotation group. Similar to the phaseless Fourier measurement, considering only an amplitude measurement in this setting creates ambiguity in the reconstruction of the SMC. This paper shows the numerical investigation of several phaseless algorithms applied to spherical nearfield antenna measurements.
