FMCW radar system and interference detection method for FMCW radar systems

摘要

The frequency-modulated continuous-wave radar system (1) has a transmitting- or receiving unit (2) which is formed to transmit radar signals (3) which are modulated by a modulation parameter and to receive radar signals (3a) which are reflected from the objects. An interference detector (6) is provided for detecting interferences in the received radar signals based on a frequency-dependent received power threshold value corresponding to the modulation parameter. The modulation parameter is a modulation slope of the transmitted radar signal. An independent claim is included for an interference detection method for a frequency-modulated continuous-wave radar system.
