| Abstract(in English) | This report explains our proposed security system using radio waves based on space-time signal processing. The proposed security system can observe whole target area, such as whole room and house. The proposed security system exploits an antenna array on the receiver side. Signal subspace spanned by eigenvector, which is unique to the propagation environment, is obtained with the antenna array. The signal subspace changes when the environment of interest changes statically or dynamically. In this report, we explain the fundamental principle of our security system and show some experimental results. Moreover, we show some applications of our security system, such as, monitoring and alarm for mislaid properties. |
