Abstract:In recent years, with the development of device-free sensing (DFS), researchers have applied it to the field of identity recognition. By taking advantage of the unique influence that different people have on surrounding wireless signals, the technology is able to identify people in a contactless way. Some progress has been made in identification by analyzing the gait information in the received wireless signals, but it needs to provide enough space for walking, which limits its application scenarios to some extent. In order to solve this problem, this paper proposes WAID, a recognition system based on human activities. Through analyzing the unique influence of different people doing the same activity on the channel state information (CSI) of WiFi signal, the identity information of people can be extracted from it. Thus, identification can be achieved by performing activities in fixed locations where there are no area requirements. The experimental results show that in the case of 2 to 6 people, the average recognition accuracy of WAID is 94.3% to 88%, and the average accuracy under six positions is 84.8%. | |||

Abstract:The position fusion of ground targets is required for forming a correct enemy situation map when a certain target is observed by a Mobile Ground Scouting System (MGSS) several times or by several MGSSs. Position error of target is the basis of fusion. The measuring model of fix ground target has been founded under the geodetic rectangular coordinates by analyzing the process of MGSS determining position of target. The theoretic distributing rule of coordinate errors is deduced according to the transfer course of errors and approximated to the normal distribution based on analyzing components of errors. The simulation has proved that the approximation of distribution rule is practicable. Fusion rule of fixed ground target has been established through selecting shape and calculating size of fusion gate. | |||
