RF/wireless indoor activity classification

Abstract Recent developments in noninvasive radar measurement of small-scale motion offer great potential for indoor activity classification in applications such as health diagnostics, health monitoring, surveillance, occupancy sensing, and animal research. Combined with wireless body area networks and indoor localization technology, the measurement and recognition of biological motion patterns will shape the future of home and workplace security, safety, and comfort. This chapter will focus on Doppler radar-based sensing systems for activity monitoring. The organization of the chapter is as follows: background information and recent developments, followed by the theory of Doppler radar sensing in activity classification, experimental results for potential applications, and related challenges.
