Popis: Every antenna measurement has an associated uncertainty, and the estimation of this uncertainty, when performed experimentally, may be more time-consuming than the nominal measurement. In this work, we investigate and test a new method for the numerical estimation of the uncertainty originating from a probe transverse error in spherical near-field antenna measurements, i.e. an improper positioning of the probe with respect to the measurement coordinate system. The method we propose exploits the spatial positioning of the probe when an error of this type is present in order to acquire the error signals numerically through the signals acquired in the nominal measurement. As a result, our method is considerably faster, since it does not require additional full-sphere measurements and, moreover, it does not occupy the antenna under test for any additional time than that required for its nominal measurement.
