Sammanfattning

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,
ie the radome, is analyzed. The transformation is based on the
surface integral representation that relates the equivalent currents
to the near-field data. The full vector formulation is used in the
analyzis but the numerical results are limited to the scalar
approximation. It is shown that defects on the radome, not localized
in the measured near field, are focused and detectable on the radome
surface.
