Abstract
In this paper, a Doppler radar for a localization of a human motion is demonstrated. In the system, we used a $8{\times}8$ phased array antenna using metamaterial phase shifters for easy and precise control of antenna beam pattern. Scanning area is a circular sector with an inscribed angle of $60^{\circ}$ and a diameter of 45m. This area is divided with 15 designated area and each area is scanned for 0.2 second. When there is a motion in a designated area, we are able to detect a frequency shift due to a Doppler effect. In this way it is possible to detect the location of motion. The experiment shows that 78% of position accuracy. The remaining 22% occurred the surroundings of the designated area.
