Abstract

See Through the Wall Radar, is a relatively new small range radar that uses electromagnetic waves to detect targets behind wall. Because of its symmetry, a conducting sphere is often used as a reference scatterer to calibrate radars and measure the scattering properties of other radar targets. In this paper, to simulate received signal for see through the wall radar, scattering model of a conducting sphere in free space is presented. Then using a dielectric sheet to represent the wall between the radar system and the sphere behind it, scattering model of a sphere behind the wall, is developed. To create the image of sphere behind the concrete wall using the signals acquired with the proposed model, Range Migration Algorithm (RMA) and coherent background subtraction is used and an image of sphere behind wall has been achieved. Simulation results reveals the suitability of the proposed model for See Through the Wall Radar received signal simulation.
