Abstract
With the rapid development of emerging smart homes applications, the home security systems based on passive detection without carrying any devices has been increasing attention in recent years. Through-The-Wall (TTW) detection is a great challenge since through-the-wall signal can be severely attenuated, and some of the existing TTW-based detection techniques require special equipment or have strict restrictions on placement of devices. Due to the near-ubiquitous wireless coverage, WiFi based passively human detection technique becomes a good solution. In this paper, we propose a robust scheme for device-free Through-the-wall Human Detection (T-HuDe) in TTW with Channel State Information (CSI), which can provide more fine-grained movement information. Especially, T-HuDe utilizes motion information on WiFi signal and uses statistical information of motion characteristics as parameters. To evaluate T-HuDe performance, we prototype it in different environments with commodity devices, and the test results show that human activity detection rate and human absence detection rate of T-HuDe are both above 93% in most detection areas.
