Abstract: “Recently, the use of Ultra Wide Band (UWB) technology has been increasing. This technology makes it possible to obtain high-resolution images of distant objects using microwave signals. A 2D ISAR algorithm was developed for defense and tomography and is used in medical approach. In this paper, the tomography algorithm is studied, using microwave similar to those used in reflection tomography. Three-dimensional images were reconstructed using two receiver antennae and one transmitter. The ISAR interferometry configuration was designed as a backprojection algorithm. When compared to 2D imaging, the signal has an elliptical range profile in the 3D observation mode. An elliptical range migration is confirmed in both theoretical and experimental results.”
