FMCW radar system and interference recognition method for FMCW radar systems

摘要

An FMCW radar system is provided having a transceiver unit which is designed to transmit radar signals, which are modulated with the aid of at least one modulation parameter, and to receive radar signals, which are reflected from objects, and having an interference detector for detecting interferences in the received radar signals based on at least one frequency-dependent reception power threshold value corresponding to the particular modulation parameters, one of the modulation parameters being a modulation slope of the transmitted radar signal. An interference recognition method is also provided.

1. An FMCW radar system, comprising:
a transceiver unit configured to transmit radar signals which are modulated according to at least one modulation parameter, and to receive radar signals which are reflected from objects; and an interference detector configured to detect interferences in the received radar signals based on a comparison of reception power of the received radar signals to at least one frequency-dependent reception power threshold value, wherein the at least one frequency-dependent reception power threshold value is set based on the at least one modulation parameter, and wherein the at least one modulation parameter is a modulation slope.
