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 bi-polar method, the reconstruction of far field can not be obtained directly. Here we proposed a novel, fast interpolation method that recovers the uniformly spaced samples of near field from the unequally spaced ones which are gathered through bipolar method.
