According to the characteristic of Through-the-Wall Surveillance (TWS),a novel TWS detector scheme is proposed which is based on sinusoidal frequency modulation and spread spectrum technologies.The experimental system is established,and some experiments are accomplished.When a person behind a thick brick wall of a 40 centimetres and the detector is 5 meters away,the system can still find living signals of human beings.The experimental results show the effectiveness of the proposed scheme.
