Abstract :
A 3-D UWB SAR has been designed to detect the positions of the targets behind the wall and identify them as well. The beam scanning is based on the mechanical movement of the wideband Tx/Rx Vivaldi array. The system transceiver and 3-D microwave beamforming algorithm are introduced in details. An experiment is performed to recover the 3-D images of a human mock-up. The demonstrated 3-D imaging results have indicated the capability of accurately locating, tracking and identifying human beings behind the wall.
