A method for measuring a radiation field in the direct vicinity of a measured object is provided. One or more antenna measurement probe(s) are moved in any desired fashion within the radiation field, and a number of high-frequency measurement points is thus recorded. During the movement of the antenna measurement probe, a position determination of a respective antenna measurement probe is conducted simultaneously with or in close temporal proximity to the capture of a respective high-frequency measurement point, in order to assign a position to each high-frequency measurement point so as to generate a spatially defined measurement point cloud. Finally, radiation patterns at any distance from the measured object may be determined from the spatial measurement point cloud by means of a field transformation method.

Method and device for measuring a radiation field

A method of measuring a directional graph of a test antenna includes disposing a plurality of measuring probes relative to the test antenna, each being disposed at a different first predetermined height above a reference plane; disposing the test antenna at a second predetermined height above the reference plane; measuring transmission characteristics relative to the test antenna between each of the plurality of measuring probes and the test antenna; determining prevailing scatter characteristics of the reference plane; and determining the directional graph of the test antenna using the prevailing scatter characteristics.
