Study on target pose and deception jamming to ISAR

The quality of ISAR (Inverse Synthetic Aperture Radar) imaging is closely related to the target pose and its motion law. Only high range resolution can be achieved, whereas can not in azimuth in some occasions. However, two-dimensional high resolution images of pre-selected target can be formed if ISAR is decoyed effectively. Combining this idea with digital false-target image synthesis theory, even more effective false target decoys are studied, making use of pose and motion information of actual target. The validity is analyzed and simulated for different pose and motion laws of actual targets. The relationship between jamming effectiveness and target pose is studied systemically. The simulation results provide valuable reference for applying deception jamming, understanding true image and evaluating jamming effectiveness.
