| Abstract(in English) | In recent years, the society is aging further. And the number of deaths that are lonely deaths have been increasing year by year. Under these circumstances, there is a growing awareness of strengthening the monitoring of the elderly living alone. Nowadays, the mainstream of sensing technology is cameras and infrared rays. However, these methods have privacy problems. To solve the problem, we aim to perform sensing using a MIMO sensor, which is a type of radio wave sensor. In this report, four elements of transmitting and receiving antennas are arranged vertically, four kinds of behaviors with different height variations are measured, and it is found that the variation of time correlation variation of the propagation channel of the received radio wave is different. Furthermore, it was found that the behavior can be estimated by simple evaluation using machine learning (CNN). |
