In recent years, Through the Wall Imaging (TWI) has become a topic of research interest due to its promising applications in home-land security situations. In this paper, the basic concept of Stepped-Frequency Continuous Wave (SFCW) for ranging the targets behind the wall is described. Imaging of targets is implemented using the back-projection algorithm. This paper also brings out the received signal model for detection of stationary human being behind the wall using SFCW approach. The detection is based on estimation of heart beat and respiratory motion. Simulation results of human detection through Doppler processing and the 2-D imaging of targets are brought out for illustration. MATLAB software has been used for the development of signal processing modules.
