Simultaneous Location and Parameter Estimation of Human Vital Sign with MIMO-FMCW Radar

Simultaneous location and parameter estimation of vital sign signal captured with a MIMO-FMCW radar sensor system is presented. The suggested system is able to deal with safety inspection emergency counter-terrorism and fire rescue. Micro-Doppler information, estimated from received signal, is used to classify heart and breath frequency of human. The Capon BF measurement algorithm is used to estimate accurate angles. The received signal synthesize precise angle information to get position of target. Measured data collected from MIMO-FMCW radar received encouraging results after these algorithms. Results of human object with deferent range or angle show effectiveness to achieve great estimation performance.
