Radar micro-Doppler signatures can be utilized for security applications like detection and assessment of human activity at airports, power plants etc. The micro-Doppler signature reflects the movement of various body parts. Using a 77 GHz radar we have obtained human micro-Doppler signatures of one or two persons, with different ways of movement, different movement directions and without or with carrying objects. We have analyzed the micro-Doppler signatures for these cases and we observe general properties of the signatures. We further suggest properties to use when designing detectors and classifiers of human targets.
