Abstract
A distance measuring apparatus and method for calculating a distance in a conducting structure are provided. One distance measuring apparatus provides for calculating a distance between a reflection body in a conducting structure and an injection point provided on an end section of the conducting structure for electromagnetic waves is provided. The distance measuring apparatus includes a transmitting and receiving device with a conduction cross-over provided at the injection point for the coaxially-inductive coupling of the transmitting and receiving device to the conducting structure in order to inject an electromagnetic wave into the conducting structure and to decouple the electromagnetic wave reflected on the reflection body from the conducting structure. The distance measuring apparatus also includes an analysis device for calculating a distance between the injection point and the reflection body from the phase difference between the injected electromagnetic wave and the decoupled electromagnetic wave.
