description

A new algorithm is applied for obtaining the near field form far field measurements. It is not only the simple DFT applied to the spectrum, but also a newer algorithm, called PDFT, which makes use of the information in the transformed domain. Its main advantage is that the resolution obtained is better than with DFT, since more information about the antenna is used. Furthermore, no iterations are applied and the best approximation in the way of minimum weighted norm is achieved.
