Abstract: 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.

Abstract: According to an example aspect of the present invention, there is provided a method comprising, receiving, from a radar, a first reflected signal and a second reflected signal, determining a reference signal of the first reflected signal and training an artificial neural network using the first reflected signal and the reference signal of the first reflected signal, upon training, determining an output of the artificial neural network associated with the first reflected signal and providing a magnitude and angle image of the radar associated with the second reflected signal based on the output of the artificial neural network associated with the first reflected signal.

Abstract: 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.

Abstract: A portable electronic navigational aid (104) e.g. for the blind (102), comprising a radio frequency, preferably millimeter wave, radar (218) with at least one transmitting (TX) channel and a plurality of receiving (RX) channels, at least one orientation sensor (220) configured to obtain data indicative of the orientation of the radar, and a processing element (210) configured to adaptively control (500, 602) the beamforming of the radar based on the data provided by the orientation sensor. A corresponding method is presented. An accessory, such as a replaceable cover, containing a radio frequency radar for attaching to an electronic host device is presented.

Abstract: 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.

Abstract: Antenna miniaturization is a big engineering challenge because of the fundamental limitations that restrict antenna performance. In the present invention a new dielectric cap loading technique for improving small antenna element performance exploiting the space capacitance is introduced. The cap loading technique can be easily realized e.g. by 3D dielectric blocks, such as ceramic blocks.
