Abstract :
In order to compute the far-field pattern of an antenna from its near-field samples, uniform sampling techniques have been widely used. If a signal is non-uniformly sampled due to probe position errors, the reconstruction of far field ran not he obtained correctly. Here, we propose a fast new interpolation method that recovers uniformly spaced samples of near-field data from the unequally spaced ones.
