Final Report Honours Project: Through-the-Wall Imaging Radar Student: Supervisors:

A through-wall imaging radar could have many applications where it is important to view a visually and physically obstructed area. Typical applications for such radar are search and rescue, police and military operations. The desired purpose of a through-the-wall system is to estimate or detect the inner content and structure of a room behind the wall, or layout of a building. Further actions, such as sending personnel inside the obscured area can be followed accordingly once the result is extracted. This project was conducted to investigate the feasibility of constructing a Synthetic Aperture Radar using a Vector Network Analyser as the waveform generator and a pair of horn antennas being moved to form a Synthetic Aperture, in order to image the objects behind the wall. The arrangement of the antennas could follow bistatic or pseudo-monostatic configuration. For each movement of the antennas, the forward gain of the environment was measured. MATLAB programs were used for focusing implementation to generate the images of the region using recorded data. 2-D image of the region of interest behind a wall has been successfully generated. The pseudo-monostatic configuration results in better cross range resolution compared to bistati
