A new method of camouflage jamming against ISAR based on compensating modulation

It is quite significant in the military field that an effective jamming can be executed against inverse synthetic aperture radar (ISAR) successfully. However, ISAR has a well anti-jamming capability, which is stronger than that of conventional radar due to its special imaging approach. Camouflage jamming with many particular advantages becomes a very effective and important jamming approach nowadays. However, it is a novel and important technologic approach that an effective camouflage jamming can be carried out against ISAR. A new method of camouflage jamming is proposed in the paper, based on principle of ISAR imaging. The compensating modulation can be employed for the ISAR signals received by jamming device to achieve camouflage jamming, based on the phase relationship between ISAR signals received by jamming device and the real returned signals of targets. The feasibility and effectiveness of the methods are verified by simulation results.
