- 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 full vector surface integral representation that relates the
equivalent currents to the near-field data.
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... (More) - Knowledge of the current distribution on a radome can be used to

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 $29-43unit{wavelengths}$ in
the frequency interval $8.0-12.0unit{GHz}$. 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)
