Abstract: A computer-implemented method for adaptive near-field data acquisition during a sampling process; it includes measuring at least one of an amplitude and phase of a field using one or more probes, wherein the measuring is performed at a plurality of points; selecting, for each point of the plurality of points, a set of neighboring points; calculating a field variation to determine the presence of a strongly varying near-field pattern; for each location corresponding to each point of the plurality of points where a varying near-field pattern is determined after the calculating of the field variation, inserting one or more new points; and for each of said one or more new points, calculating a field variation to obtain a higher near-field resolution for said each location where a near-field variation is determined.

Abstract: A ground filtering source reconstruction method and system, for a near field measurement system comprising a scanner board with an array of integrated probes that are backed by a ground plane and at least one coupled RF receiver that captures near-field data from an antenna-under-test (AUT) or device-under-test (DUT).
