| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A passive localization method (Device-Free Localization: DFL) is useful in disaster scenarios as well as daily life applications because it does not require users to carry a terminal. RTI (Radio Tomographic Imaging), which is one of the passive localization methods, maps the location of a moving target in a target area using many wireless links in an RF sensor network. In our previous study, we proposed the Multipath-RTI method, which reduces the number of sensor nodes significantly and achieves highly accurate localization by separating the multipath components among sensor nodes. We also developed a method of separating and extracting propagation paths by beamforming using distributed MIMO sensors and confirmed its effectiveness through simulations. In this paper, we propose a new method to measure the propagation paths of multiple MIMO links between anchor nodes in a short time by using four switched-antenna MIMO channel sounders configured based on a software radio developed in our previous study. The performance of the system was confirmed through evaluation experiments. | |
