Abstract
Method and system for deriving interbeat interval (IB1) measurement of subject. A radar device receives a reflection radar signal reflected from subject. A signal portion of reflection radar signal at a range of subject is extracted, the signal portion collected over predefined intervals and consisting of an in-phase component and a quadrature component. The signal portion is filtered by applying a complex valued continuous wavelet transform (CWT) to derive a time domain ballistocardiograph (BCG) signal with cyclically repeating features, such that the time displacement between repeating features of the derived BCG signal is representative of a first heartbeat interval measurement of subject. At least one segment of the BCG signal over a selected time duration may be identified using a matrix profile technique, such that the time displacement between successive identified segments is representative of a second heartbeat interval measurement. Radar signal may be THz/millimeter-wave and FMCW radar signal.
