Non-line-of-sight Holographic Imaging Algorithm for Near-field Millimeter Wave Radar
摘要
Abstract
Non-line-of-sight(NLOS)radar imaging technology is designed to reconstruct hidden targets under the interference of obstacles,and has great application potential in autonomous driving,regional security and other fields.Based on multi-input multi-output(MIMO)millimeter-wave radar,a two-dimensional(2-D)imaging technique using multi-path reflected signals to invert the scattering characteristics of hidden targets in radar non-line-of-sight is proposed.In this scheme,a 2-D equivalent uniform array is synthesized by a MIMO millimeter wave radar scan with mounted on high precision rail,multi-reflection echo is used to reconstruct hidden targets is images.In addition,the NLOS imaging model is established and a high precision imaging method based on 2-D wave number domain algorithm and mirror symmetry is proposed.In this method,the prior knowledge of the NLOS targets and the reflecting wall is extracted by cross-sectional imaging of the hidden targets.Then,the prior knowledge is combined with the principle of mirror symmetry to achieve the high-precision focusing of the coronal plane of the NLOS targets to obtain the target contour.Finally,the effectiveness of the proposed algorithm is verified by NLOS millimeter wave imaging system.关键词
