Accurate Radar-Based Heartbeat Measurement Using Higher Harmonic Components

This study proposes a radar-based heartbeat measurement method that uses the absolute value of the second derivative of the complex radar signal, rather than its phase, in combination with the variational mode extraction method, which is a type of mode decomposition algorithm. We show that the propo...
