Reconstruction of Equivalent Currents Using a Near-Field Data Transformation - with Radome Applications

In English

Författare

Summary, in English

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.
