| Abstract(in English) | This report introduces human activity sensing systems using radio waves in ambient intelligence. First we introduce the proposed system based on array signal processing, referred to as array sensor. The array sensor exploits an antenna array on the receiver side and decomposes received signals into eigenvectors and eigenvalues. The array sensor exploits these components depending on its applications. Using machine learning based on these components, the array sensor can classify several complex states and activities. The proposed system can also realize tag-free localization. Therefore, it is expected for monitoring and security applications. Second we introduce the proposed human activity sensing and tracking system using MIMO (multiple-input multiple-output) radar. The proposed MIMO radar exploits Doppler frequency information so that it can compose spatial-temporal virtual array and achieve higher estimation accuracy. We also introduce a human activity classification and localization algorithm using a bistatic three frequency continuous wave (CW) radar. The proposed algorithm using a bistatic three frequency CW radar can classify human activities and track human beings. Moreover, we introduce non-contact vital-sign measurement techniques based on Doppler radar. |
