基于UWB隐藏目标探测接收装置设计

基于低频电磁波对非金属介质的强穿透性和UWB脉冲信号在距离向的高分辨特性，采用超宽带（UWB）脉冲信号的低频部分实现穿墙探测的设想，研究了超宽带穿墙探测雷达的运动目标回波信号模型，根据运动物体的多普勒频移原理，探讨采用相关检测技术实现非金属墙壁后面的运动物体的检测问题。

The Design of Ultra-Wideband Radar Receiver for Hidden Target Detection

This paper firstly analyzes the property of the low frequency electromagnetic wave,which can penetrate many types of non-metallic materials,and the ability of ultra-wideband(UWB) impulse signal which has high range resolution.Then the methods are discussed for conducting surveillance through walls,detecting and locating the moving persons behind the partitions.The schematic diagram of through-wall detecting radar(TWDR)and the pulse-echo models of moving target are shown.Finally detection of moving target by detection of the Doppler shift of radiation scattered or reflected by the target when illuminated by such radiation is discussed,which implements by correlate detection technology.
