Abstract :
The imaging of objects within an enclosure using short electromagnetic pulses is investigated. A simulated image of a metallic cylinder within a plywood box is constructed using the numerical scattered field found by solving an integral equation. Comparison with images found experimentally shows good agreement, and the object is easily detected through the walls of the box. Multiple objects placed within the plywood box are imaged with similar clarity
