Abstract
A method and apparatus for detection of blocking of a frequency-modulated continuous-wave, FMCW, radar device. A first signal being a first transmission signal including an object detection signal is transmitted. A second signal being a frequency offset signal relative the first signal is transmitted. A reception signal including 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.
