| 摘要 |
The invention relates to a method for measuring a physical variable, in particular a distance, having the following steps: at least the first transmission signal (s1) with a predefinable first signal shape is transmitted over a first transmission link (190a) whose transmission function depends on the physical variable to be measured, wherein a first reception signal (s1') is obtained at an output of the first transmission link (190a), at least a first reference signal (sr) with a predefinable reference signal shape is transmitted over a reference transmission link (190r), wherein the reference transmission link (190r) preferably has a known transmission function, and wherein a reference reception signal (sr') is obtained at an output of the reference transmission link (190r), and the first reception signal (s1') and the reference reception signal (sr') are analysed in order to determine the physical variant. |
