Abstract :
A three-antenna InISAR imaging method is proposed to reconstruct a 3-D image of high speed space target. Aiming at the key problem of high radial velocity between radar and target during the imaging duration which will defocus the ISAR image, we present a new Radon-XWV detector formed by two interferometric channel signals to estimate the velocity in each pulse and to compensate the echo signal before imaging process. Simulation result shows the effectiveness of the method.
