Identification of the current distribution on a radome from near-field measurements

• Information about the equivalent 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 the equivalent current distribution is analyzed. The transformation is based on a singular value decomposition of the surface integral equation that relates the equivalent current to the near-field data. The attempt is to develop a mathematical model that easily can be used for arbitrary geometric structures. The symmetries of a specific problem is used to reduce the computational complexity. Both synthetic data and measured data are used to verify the algorithm.
