Automatic human target detection of ultra-wideband through-wall radar

This paper presents a time domain, moving target detection (MTD) processing formulation for detecting human motion behind walls. The proposed MTD processing formulation consists of exponential averaging background subtraction, ordered statistics constant false alarm rate detection (OS-CFAR) and binary accumulation. We demonstrate the effectiveness of the MTD processing formulation using data collected by an impulse, ultra-wideband through-wall radar. We also analyze the false alarm and detection rate of human with static standing and radial movement.
