Abstract
This paper presents a motion detection radar sensor using metamaterial (MTM) leaky wave antennas (LWAs) operating in the 24 GHz band. Utilizing continuous-wave Doppler radar integrated with MTM LWAs to perform frequency-space mapping over the azimuth angle, we can detect multiple human motion in the indoor environments. In addition, the moving distances of different people can be obtained by analyzing the baseband signals at different carrier frequencies.
