This paper presents the results of our experimental investigation into the radar micro-Doppler signatures (MDS) of various human activities both in free-space and through-wall environments. The collection of MDS signatures was divided into two categories: stationary and forward-moving. Each category of MDS signatures encompassed a variety of movements associated with it, adding up to a total of 14 human movements. Using a 6.5-GHz C-band coherent radar, the MDS of six human subjects were gathered in free-space and through-wall environments. The MDS for these cases were analyzed in detail and the general properties of the signatures were related to their associated phenomenological characteristics. Based upon the MDS, specific features for designing detectors and classifiers of human targets performing such movements are extracted.
