Abstract

For realizing automated monitoring of the behavior and preferences of residents for smart homes/smart building applications, device-free localization techniques using radio propagation characteristics have gained interest. In such techniques an environmental information should often be known in advance. This study developed the multi-dimensional Kirchoff migration method to estimate a room geometry for indoor localization and the estimation accuracy was evaluated by ray-tracing simulations. By utilizing millimeter-wave radio systems, multi-dimensionality in terms of time-of-flight and angle-of-arrival/departure and high resolution in channel impulse responses offer high estimation accuracy. Moreover, the feasibility was demonstrated via the laboratory test measurements using our channel sounder.
