There is provided detection of blocking of a frequency-modulated continuous-wave, FMCW, radar device. A first signal being a first transmission signal comprising an object detection signal is transmitted. A a second signal being a frequency offset signal relative the first signal is transmitted. A reception signal comprising at least a received version of the second signal is received. Blocking of the FMCW radar device is determined by identifying a blocking pattern in the received version of the second reception signal. |
