Carrier frequencies from 2 GHz to 30 GHz under three types of thoracic movements are verified by using a broad band multi-channel Doppler radar system. The results show that there are different favorable vital-sign detection frequencies for different respiration conditions.MFCW radar | microwave | millimeter-waveconference paper10.1109/iWAT57058.2023.101717502-s2.0-85166374262https://api.elsevier.com/content/abstract/scopus_id/85166374262
