A new approach called the window increasing technique (WIT) is presented to discriminate mathematical and physical poles extracted from a noisy antenna response. The principle of the WIT is to apply a pole extraction method on several windows of the response and then to observe the stability of the extracted poles. To compare the WIT with the classical window moving technique (WMT), these two techniques are applied on the electric far‐field backscattered by a dipole antenna. It is shown that, in the presence of noise, the WIT allows finding more physical poles with a good accuracy than does the WMT.
