摘要
基于超低频电磁波的强穿透性、低衰减率的特点,提出了基于超低频电磁波的穿墙生命探测器设计方法,并对其工作原理进行详细的论证,包括利用双通道相关检测方法来得到目标信号和利用人体生命信号的特征来对目标信号进行识别,并通过仿真对其进行验证。仿真结果表明:这种基于超低频电磁波的探测器可以实现对障碍物后目标对象的探测。
Due to the strong-penetrability and low-attenuation rate characteristics of super low frequency （SLF） electromagnetic wave, a novel TWS detector scheme based on SLF electromagnetic wave is proposed. The principle of detector is demonstrated in details, including how to gain the target signal based on the method of double- channel correlation inspection and how to identify the target signal due to the characteristics of the human life signal. A simulation experiment is established to validate it. The simulation results show that the target behind barriers can be detected by the detector based on SLF electromagnetic wave.
