摘　　要：为获知穿墙雷达技术发展脉络以及预测未来可能的发展趋势,对近年来穿墙雷达研究领域中的墙后人体目标探测技术的发展情况进行了梳理.围绕墙后人体目标探测中的微多普勒谱识别、二维运动目标检测,以及三维人体目标高分辨成像等关键技术,对国内外公开发表的相关文献进行了归纳总结.结果表明,穿墙雷达已经在墙后人体目标的生命特征提取、运动行为监测、动作姿态识别等应用领域取得了长足进步.随着相关研究的深入,穿墙雷达系统开始表现出轻型化、小型化、低成本化的特点,而对应的处理算法则向更加智能化方向发展.In order to know the development and to predict the possible trends of through-the-wall detection,this article reviews the development of human target detection behind the wall in the field of through-wall radar research in recent years.Aiming at the three key technologies involved in human targets detection behind the wall,micro-Doppler spectrum recognition,two-dimensional moving target detection,and high-resolution three-dimensional imaging of human targets,we summarized the relevant literature published at home and abroad.The results show that through-the-wall radar has made great progress in application fields such as life feature extraction,motion behavior monitoring,and gesture recognition.With the development of related research,through-the-wall radar systems are beginning to show characteristics of lightweight,miniaturization,and low cost,and the corresponding processing algorithms are moving more intelligently.
