AB  - Radar-based noncontact physiological signals monitoring is meaningful for daily 
      health monitoring, post-disaster rescue, and public security. This paper focuses 
      on the theoretical and experimental study of noncontact respiratory and cardiac 
      motion signals separation by remote sensing using a four-dimensional (4D) imaging 
      radar. To adaptively separate respiratory and cardiac motion patterns, we propose 
      a variational mode separation (VMS) algorithm. VMS is established on optimizing a 
      variational problem to separate different modes. It minimizes the energy overlap 
      of the heartbeat and respiration signals as well as their harmonics with an 
      equality constraint. Both simulation and real scene data results show that the 
      proposed VMS algorithm is suitable for separating the weaker cardiac motion 
      pattern from the strong respiratory motion pattern, restraining the influence of 
      respiration harmonics on the heartbeat component. Furthermore, we have 
      implemented continuous remote monitoring of respiratory rate (RR) and heart rate 
      (HR) by employing the proposed method in a real scene. The results validate the 
      consistency with the reference respiration belt and electrocardiogram (ECG). The 
      root mean square errors (RMSEs) of RR and HR for the remote measurement are 0.13 
      breaths per minute (brpm) and 1.7 beats per minute (bpm), respectively.
