| Zusammenfassung: | A sensor system for detecting at least one dimensional variable of a rotating object (
30
) includes a plurality of sensors (
33
) disposed on the rotating object (
30
) that are sensitive to the dimensional variable and an antenna array (
11
) for supplying the sensors (
33
) with high-frequency energy and for receiving a high-frequency signal, modulated by the variable to be detected, from the sensors (
33
). The sensors are disposed on the object (
30
), distributed in the circumferential direction, and the antenna array (
11
) has a directional characteristic (
34
) for transmission and/or reception which is stationary with respect to a coordinate system not rotating with the object (
30
) and which includes only a subregion (
32
) of the object (
30
). |
