Applicability of multiple impulse-radar sensors for the recognition of a person’s action

The research reported in this paper is devoted to the impulse-radar technology when applied for non-intrusive monitoring of elderly persons. Specifically, study focused on a novel approach interpretation data acquired by means multiple sensors, leading determination features be used recognition monitored person’s actions. measurement are first transformed into three-dimensional coordinates person; next, those as basis characterising movement that person. results experimentation, based real-world data, show sensors may successfully highly accurate actions such walking, sitting, and lying down, although accuracy significantly affected quality trajectories which turn configuration within area.
