Abstract
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... (More)

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). (Less)
