Applicability of multiple impulse-radar sensors for estimation of person’s three-dimensional position
AbstractThe research reported in this paper is devoted to the impulse-radar technology when applied for unobtrusive monitoring of elderly persons. The study is focused on the development of methods for estimation of the three-dimensional movement trajectories which could be used for the detection of falls and harmful long lies after the falls. The developed methods include two methods for smoothing the trajectories of the distance between the monitored person and the impulse-radar sensors, and two methods for transformation of the smoothed distance trajectories into the three-dimensional movement trajectory. The results of the preliminary experimentation, based on real-world data, show that multiple impulse-radar sensors may be effectively used for estimation of the three-dimensional position of a moving person, although the estimation of the height-component is most uncertain.
