System and method for observing and quantifying body movements.

摘要

System for observing and quantifying body movements, comprising a Doppler radar unit transmitting on the one hand high frequency electromagnetic waves in the direction of the body on body part of the person in which said body movements are appearing and receiving on the other hand reflected electromagnetic waves and converting said waves into signal trains, Said system comprises a circuit recovering a signal from the eventually amplified signal trains, the amplitude of which signal is a function of the amplitude and/or the frequency of the incoming signal train.
