Abstract

In this paper, we demonstrate a Doppler radar system with a phased array antenna and run an experiment to find the position of a target by detecting the respiration signal of a human being. The system consists of a 2×4 phased array antenna (PAA) and several passive RF circuits such as a power divider, a circulator and a mixer. For the PAA, left-handed transmission line (LHTL) based phased shifters are used. Three different places which are 3m away with -20°, 0°, +20° angle point from the front side of the PAA are set for the experiment. The results show that it is possible to detect the position of the respiration by changing the main beam angle of the PAA.
