Bio-radiolocation method at chest wall motion analysis during tidal breathing

摘要

Influence of chest wall surface motion in bio-radar signal during tidal breathing was researched. A high-speed camera and multi-frequency radar with signal step modulation were simultaneously applied. The model of chest motion during quite breathing was used. Pairwise correlation coefficients for all the markers on the chest wall given in the model were calculated. The correlation of data from high-speed camera and bio-radar was found. Two methods were compared.
