Interferometric ISAR imaging for RCS and three-dimensional target characteristics measurements

Target characteristics are measured using variable methods, interferometric ISAR technology is used to get three dimension signature and RCS from a target. The model of interferometric ISAR is set up, the structure of the system with a single transmitter and two receivers is designed. Then eight scatterers model is supposed, two ISAR images can be got at the same time after the back projection reconstruction algorithm, and the inteferometric image can be got. Numerical simulation verifies that this method is available.
