Biometric radar system and method for identifying persons and positional states of persons

摘要

A biometric radar system and method for identifying a person's positional state are generally described herein. The biometric radar may phase adjust a sequence of radar return signals received through two or more receive antennas to remove at least some phase noise due to the stationary objects. The biometric radar may also 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 may also combine and weight the segmented radar returns for each biometric feature to generate weighted classifications for a feature extraction process.
