The present disclosure relates to a radar apparatus including a transmitter for transmitting a frequency-modulated continuous-wave radar signal, wherein the transmitter is configured to generate the continuous-wave radar signal with a sinusoidally varying modulation frequency, a receiver for receiving a reflection signal of the frequency-modulated continuous-wave radar signal, which is reflected by at least one object, and for mixing the reflection signal with the frequency-modulated continuous-wave radar signal in order to obtain a downmixed reception signal, and a device for correlating the downmixed reception signal with at least one pattern signal which is based on the modulation frequency and a predetermined distance.
