1. A biometric radar comprising: phase adjusters to phase adjust a sequence of radar return signals received through two or more receive antennas, the phase-adjusting removing at least some phase noise due to stationary objects; a signal processor to segment the phase adjusted radar return signals into a plurality of multi-resolutional Doppler components, each multi-resolutional Doppler component being associated with one of a plurality of biometric features; and a non-linear convolutional neural network to combine and weight the segmented radar returns for each biometric feature to generate weighted classifications for a feature extraction process.
