A novel non-contact vital-sign sensing algorithm for use in cases of multiple subjects is proposed. The approach uses a 24 GHz frequency-modulated continuous-wave Doppler radar with the parametric spectral estimation method. Doppler processing and spectral estimation are concurrently implemented to detect vital signs from more than one subject. revealing excellent results. https://safeersappliancers.shop/product-category/bosch-ppq7a6b90-serie-6-75cm-tempered-glass-5-burner-gass-hob-black/
