Monitoring living facilities by multichannel radar

摘要

According to an example aspect, there is provided a method comprising scanning a field of view using a plurality of radar channels of a multichannel radar, generating, a radar image on the basis of results of the scanning, wherein the radar image comprises image units comprising phase information, and determining, by the radar or the processing unit connected to the radar, a presence of moving targets within the field of view of the radar on the basis of phase and/or amplitude changes of the image units between scans, wherein the field of view being scanned within a frequency range from 30 to 300 GHz, the image units comprising amplitude information, and identifying from the radar image, by the radar or the processing unit connected to the radar, separate sets of image units on the basis of the amplitude and/or phase information of the image units.
