Accurate imaging of a moving target in shadow regions with UWB radar using Doppler effect

This paper presents an imaging method for a target in blind areas of a room. We have developed an accurate imaging method for an indoor object in blind areas, but the estimated range of the imaging is restricted because of the mutual interference of indoor multi-path echoes [1]. In this paper, we extend this conventional method for a moving target and resolves the mutual interference using the Doppler effect. Numerical simulation shows that the proposed method achieves wide-range imaging of a target and accurately estimates target velocity.
