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.
