Popis: The robust estimation of far-field radiation pattern from the near-field measurement data, which are distorted by additive noise and random impulses, is suggested. The proposed technique is based on the two-stage algorithm. The first stage is to determine the radiation sources from the data of near-field measurements by the “dual method of minimum spatial extent.” The second stage is to calculate the far-field radiation pattern from the restored source distribution. The radiation sources are modeled by a set of ideal Hertzian dipoles. The case of the one-dimensional array of electric dipoles is considered. The basic features of proposed technique are briefly discussed and numerical simulations are presented.
