Abstract
A method for locating defects in a signal transmission path by generating an HF signal having a frequency fand a signal modulated by a predetermined type of modulation; generating a HF signalhaving a frequency f; generating an intermodulation product in the form of an intermodulation product signal having frequency ffrom HF signalsandintroducing the HF signalsandinto the signal transmission path at an introduction point; receiving an intermodulation product from the HF signalsandat a defective point and reflected back and corresponding to the generated intermodulation product, in the form of an intermodulation product signal; determining a time lag tbetween the generated intermodulation product signal and the received intermodulation product signal by a cross-correlation and calculation of a length L between the introduction point and the place of signal reflection, from the time lag t.
