摘要

The High-frequency Electromagnetic Life Detection System is based on the Doppler principle. The emission electromagnetic waves can penetrate certain barrier to reach the human body buried under the ruins. Human physiological movements cause the surface of the body slight movements. The slight movements related with amplitude% phase and frequency of the reflected signals. Analysis of reflected signals, we can get the slight movements information. The reflected signals mainly include Doppler frequency shift information causing by the slight movements and the fixed object reflectd signal. The fixed objects have a stronger reflected signal than the reflected signal causing by human slight movements. The human slight movement signal is useful information, the reflected signal from the fix object is noise. How to quickly and efficiently remove the reflected signal in the strong clutter signal interference is the key of this system.
