Abstract(in English) A Doppler radar has been acquired as a non-contact heartrate measurement method. Non-contact heartbeats measurement has been phenomenal importance of health care supervision because without attached any sensors to the body Doppler radar allows long term monitoring which make comfortable to patients. The proposed method bispectrum estimation can detect the heartrate accurately after removing the receiving noise. Mitigate the noise influence in the receive signal, we investigate the efficiency of bispectrum estimation by non-contact heartrate (HR) monitoring 24-GHz Doppler radar. Bispectrum has two frequency spectra and describes the dependency between these spectra. Bispectrum and higher-order-statistics is zero for white Gaussian noise. For that the bispectrum estimation accuracy can estimate the heartrate accurately. Also, the bispectrum has the possibility to reduce the noise influence and can detect the accurate heartrate estimation.
