Abstract: 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.

Abstract: 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.

Abstract: A method and apparatus for wireless transmission of electrically complex or phase-critical signals includes a device for measuring the length of a transmission route to a moving platform, and a device for transmitting complex measuring or reference signals. According to the invention, components of the device for transmitting the signals are arranged adjacent components of the device for measuring the length of the transmission route, so that changes of the length of the transmission route are the same for both devices.

Abstract: A high-frequency measuring enclosure for measuring large test objects is formed by an air-supported membrane or textile construction of a spherical or ellipsoidal contour, which is substantially pervious to electromagnetic radiation. For absorption of residual electromagnetic radiation that may be reflected by the interior of the surface, the floor is covered with absorber material.
