Abstract

In order to construct the far-field pattern of an antenna in the time domain from its near-field samples, uniform sampling techniques have been widely used. If a signal is unequally sampled due to probe position error, the reconstruction of far-field can not be obtained correctly. Therefore, we propose a method that first recovers uniformly spaced samples of the near-fields from their unequally spaced samples by 2-dimensional nonuniform interpolation techniques, and then proceeds to the computation of the far-field by near-field to far-field transformation. In this paper a comparative survey of some recent interpolation techniques is presented for finding their advantages and disadvantages of using them in our method.
