摘要：
In this manuscript, the problem of estimating human vital signs through a plurality of single-input multiple-output frequency modulated continuous wave radars is investigated. A novel algorithm for real-time estimation of heart rate and respiration rate, and for apnea detection is developed. It employs a selection combining technique and a filtering method inspired by Bayesian filtering principles. Our experimental results evidence that the proposed algorithm, tested on commercial radar devices, outperforms well known vital signs estimation methods available in the technical literature at the price of a limited increase in computational complexity.
