摘要： According to an example aspect of the present invention, there is provided monitoring living facilities by a multichannel radar. A field of view within a frequency range from 1 to 1000 GHz, for example between 1 to 30 GHz, 10 to 30 GHz, 30 to 300 GHz or 300 to 1000 GHz, is scanned using a plurality of radar channels of the radar. Image units comprising at least amplitude and phase information are generated for a radar image on the basis of results of the scanning. Information indicating at least one error source of a physical movement of the radar and interrelated movements of targets within the field of view are determined on the basis of the image units. Results of the scanning are compensated on the basis of the determined error source. A radar image is generated on the basis of the compensated results.

摘要： According to an example aspect of the present invention, there is provided image units for vital sign monitoring by a multichannel radar scanning a field-of-view and a microwave imaging radiometer sounding the field-of-view. 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. Thermal information or information determined based on the thermal information obtained by the sounding is combined with the image units of the moving targets. In this way vital signs may be monitored based on movement and thermal information of the image units.
