Three dimensional imaging for through-the-wall human sensing

Through the wall sensing is seeing a rapid growth with the present day technology. Particularly Ultra Wideband (UWB) technology paves the way for this. Three dimensional imaging of humans behind the walls, foliage or any other rubble gives information which can help to save lives. This paper simulates a human like structure with the environment of being behind wall and extracts the three dimensional imaging of the human structure. Electromagnetic signals were transmitted and based on the received echoes after processing a 3D Imaging is obtained. Signal processing aspects before imaging and the method used for obtaining the tree dimensional imaging is also discussed.
