摘要
超宽带(UWB)技术自被提出以来,由于其功耗低、保密性好、穿透能力较强、可共享频谱资源等特点,已经在空间电子领域取得了极大的发展和应用。文章详细论述了一种能够穿越障碍物的超宽带雷达系统,并描述了该系统如何结合新的信号处理方法探测人体生命信号。文章首先提出了超宽带雷达的一种基本结构,然后分析了其各个模块硬件电路的设计方案。最后基于这种超宽带雷达,实现了人体生命探测的功能,并给出了探测人体生命信号的结果。最终实验结果表明,文中设计在超宽带系统研究方向和空间电子领域具有一定的价值和应用前景。
Since the ultra- wide band (UWB) technology was brought up, it has been greatly developed and widely used in space electronics, for low power consumption, fine confidentiality, good penetration ability and spectrum compatibil- ity. So a kind of UWB radar system is introduced in detail which can go through obstacles. It is also described how to detect human life signals with a new signal-process method. Firstly, a basic architecture of UWB radar structure is presented. Then the hardware designs of each module are analyzed. Based on this radar system, human life signals can be detected. The detect results are presented which demonstrate that this paper has good research values and application prospects in UWB research and space electronics.
