超宽带穿墙探测雷达的运动目标检测技术

Detection for Moving Target Based on Ultra Wideband Through-Wall Detecting Radar

提出了利用低频超宽带(UWB)脉冲信号实现穿墙探测的设想,研究了超宽带穿墙探测雷达(UWB-TWDR)的运动目标回波信号模型,并基于运动目标回波信号的相关性,利用相干叠加原理对多次观测的结果实现运动目标的检测。最后通过具体的穿透混凝土砖块墙壁实测实验验证了上述设想和算法。

This paper firstly analyzes the property of the low frequency electromagnetic wave which can penetrate many types of non-metallic materials. Then the methods of conducting surveillance through walls and detecting the presence of living persons behind barriers are discussed. The models of moving target are shown and a moving target detecting algorithm is performed on coherency technique. Finally the performance of the Ultra Wideband Through-wall Detecting Radar(UWB-TWDR) is validated by the experiments for penetrating an ordinary concrete wall.
