摘要：

This paper reports human body localization while walking in an indoor environment by multiple-input multiple-output ultra-wideband (MIMO-UWB) radar systems. Reflections from a human body are detected from the UWB pulse response. In indoor environments, reflected waves from the human body must be separated and extracted from the other reflected waves. In this research, human body reflected waves are extracted using the impulse response difference between consecutive snapshots without using pre-measured response characteristics for the room. When six antennas are used in a room of 5 m(2), the body position is localized with an RMS error of 20 cm or less.
