Device for length calibration of waveguides for guiding millimeter waves of millimeter radar, has two approximately parallel guided waveguides, where transmitted radar signals are guided to temperature measuring point loaded in turbine case

摘要

The device has two approximately parallel guided waveguides (1,2), for guiding a transmitted radar signals (6) of a millimeter radar (7). The transmitted radar signals are guided to temperature measuring point loaded in a turbine case. The backscattered radar signals are re-fed for reception in radar system. A coupling element (3) is positioned near the measuring point between the waveguide for signal transmission and waveguide for received signal. A part of the transmitting power is directly coupled by the coupling element into the waveguide. An independent claim is also included for a method for length calibration of waveguides for guiding millimeter waves of a millimeter radar.
