- Knowledge of the current distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to its equivalent current distribution on a surface of arbitrary material, ie the radome, is analyzed. The transformation is based on a vector surface integral representation that relates the equivalent currents to the near-field data. Experimental verification using measured near-field data originating from a reflector antenna is then examined. The field irradiates a radome whereupon it is measured on a cylindrical surface. The quantity of data is large since the height of the radome corresponds to 29-43,,wavelengths in the frequency interval 8.0-12.0,,GHz. The presence of axial symmetry enables usage of the fast Fourier transform (FFT) to reduce the computational complexity. Furthermore, the problem is regularized using the singular value decomposition (SVD).
