摘要
Embodiments of a biometric radar system and method for identifying a person's positional state are generally described herein. In some embodiments, the biometric radar includes phase adjusters to phase adjust a sequence of radar return signals received through two or more receive antennas to force coherency against stationary objects and remove at least some phase noise due to the stationary objects. The biometric radar also includes a signal processor to segment the phase adjusted radar return signals into a plurality of multi-resolutional Doppler components. Each multi-resolutional Doppler component may be associated with one of a plurality of biometric features. The biometric radar system also includes a neural network to combine and weight the segmented radar returns for each biometric feature to generate weighted classifications for a feature extraction process. Biometric radar system may determine whether the person is walking, talking, standing, sitting, or sleeping.
