| 摘要 |
The invention relates to a method for detecting high-frequency signals (22), having the following method steps: separating a high-frequency signal (22) into a raw signal (3) and a reference signal (4); damping the raw signal (3) so as to form a damped signal (9), the damping process being carried out on the basis of the frequency of the raw signal (3) in a manner corresponding to a damping characteristic; rectifying the damped signal (9) such that a first DC voltage (15) is generated; rectifying the reference signal (4) such that a second DC voltage (16) is generated; ascertaining a damping from the ratio between the first and second DC voltage (15, 16), said ratio corresponding to a damping factor of the damping of the raw signal (3); and determining the frequency of the high-frequency signal (22) from the damping factor and a damping characteristic (17). |
