Beschreibung
Zusammenfassung:	According to an example aspect of the present invention, there is provided monitoring living facilities by a multichannel radar. Field of view of the radar is scanned within a frequency range from 30 to 300 GHz. Radar image is generated on the basis of results of the scanning. Separate sets of image units are identified from the radar image on the basis of the amplitude and/or phase information of the image units of the radar image. Presence of moving targets within the field of view of the radar is determined on the basis of phase and/or amplitude changes of the image units between scans.
