title: Life signal extraction in through-the-wall surveillance.
abstract: Technology of Through-the-Wall Surveillance (TWS) is explosively developing in recent years and widely interested. This paper proposes the general TWSR system architecture and the whole signal processing units, both of which help researchers to design or improve the system performance conveniently. We also analyze the selection of radar signal and filter, and their influences on the system performance. Finally, our simulation demonstrates that our solution can successfully distinguish the breathing and heartbeat information from the echo signal of one stationary person.
