Ultra Wide X-Band Microwave Imaging of Concealed Weapons and Explosives Using 3D-SAR Technique

الملخص EN

In order to detect and image concealed weapons and explosives, an electromagnetic imaging tool with its related signal processing is presented.

The aim is to penetrate clothes and to find personal-born weapons and explosives under clothes.

The chosen UWB frequency range covers the whole X-band.

The frequency range is justified after transmission measurements of numerous clothes that are dry or slightly wet.

The apparatus and the 3D near-field SAR processor are described.

A strategy for contour identification is presented with results of some simulants of weapon and explosive.

A conclusion is drawn on the possible future of this technique.
