A device for the calibration of a radar - distance measuring apparatus and method for calibrating a radar - range finder

摘要

Is described and illustrated a device (1) for the calibration of a radar - distance-measuring apparatus (3), in particular for the calibration of a radar - level measurement instrument, with at least one measuring section (4) for coupling to at least one transmitter - and / or receiving unit (7) of the material to be calibrated radar - range finder (3), wherein the measuring section (4) a dielectric waveguide (5) for guiding a measurement signal comprises. The object, a device for the calibration of a radar - distance-measuring apparatus with which, in a particularly simple and efficient manner, a calibration is made possible, is achieved by the fact that, on the dielectric waveguide (5) at least one impedance disturbance (8) is arranged in such a way that in operation, at least the evanescent field (13) of the measuring signal is reflected.
