A Warping Strategy and MPME Algorithm for Data Reduction in Near-field Antenna Measurements

In the framework of antenna measurement techniques, the most frequently adopted sampling strategy employs a sampling step equal to the wavelength. In the case of large antennas, particularly fot active antennas with multiple beams and functions, this can lead to the acquisition of a large number of points and a consequent increase in measurement times. in this work, a point reduction strategy exploiting the knowledge of some priors on the antenna under test is proposed.
