Abstract
A method for detecting a vital sign of a subject () comprises: receiving () a reflected radio frequency signal from the subject (), the reflected signal being based on a transmitted signal, which is Doppler-shifted due to mechanical movements corresponding to the heart rate and/or the respiratory rate; dividing () a baseband signal into a sequence of sliding windows (), each sliding window () representing a time interval; estimating () a vital sign parameter in at least one sliding window (); determining () whether a vital sign parameter may be reliably estimated in at least one sliding window (); on condition that the vital sign parameter may not be reliably estimated in a sliding window (), determining () a vital sign parameter of the sliding window () based on vital sign parameters estimated in a plurality of windows representing time intervals close to the time interval of the window ().
