Abstract:We proposed a phase accumulation to improve the SNR and accuracy on remote heartrate measurement based on multiple chirps mmwave FMCW radar. However, specification of radar module has continued to be upgraded and it has become clear that increasing number of the accumulative phases may actually worsen the heartrate estimation accuracy, depending on subject and time of experiment. Therefore, this article proposes adaptive adjusting accumulative number of phases, for remote heartrate measurement based on mm-wave… Show more
