Comparative Analysis on Fall Detection of Elderly People

Abstract

Accidental falls have been one of the most serious issues concerned with the elderly and an important research area in the life signs domain. The injuries can have a serious effect on their lives. Furthermore, if the elderly remain lying down for a long period post-fall, then there is a chance of suffering from serious complications which increases. Such complications should be avoided beforehand. Thus, in the field of life signs, it is important to achieve a methodology to study fall detection and prevent it. This paper reviews the work as to how to detect movement of the human beings which causes a change in radar signals and then produce corresponding Doppler signatures. These Doppler estimations acquired are utilized to recognize the diverse human movement utilizingmicro-Dopplersignal. Themeasurements which are obtained will yield the results of the various human motions at different ranges and simulate thesame.
