Signal Processing in a Two-Module Radar System for Monitoring of Human Position and Movements in an Indoor Environment

摘要

The research reported in this paper is related to an assistive technology that may be used by healthcare services for elderly and disabled people. A system for non-intrusive monitoring of the movements of such persons in their home environment, based on impulse-radar sensors, is adressed. A large family of new procedures for the estimation of position and walking velocity of a monitored person, on the basis of data acquired in such a system, is presented. These procedures are compared using measurement data acquired in laboratory conditions. A set of Pareto-optimal procedures is selected.
