The study of multi-false targets synthesizing technology against chirp ISAR

To realize multi-false-targets deception jamming against inverse synthetic aperture radar, it is important to produce a good signal that contain multi-false-targets information. In this paper, a new phase modulation coefficient is proposed, accordingly the method to synthesize multi-false-targets signal is proposed. The scheme that can synthesize the signal of multi-false-targets is given. The theory analysis and simulation tests are also done. The results demonstrate that the proposed phase modulation coefficient and the method are feasible and effective. Comparing with the original phase modulation coefficient which can only produce a single false target, the proposed phase modulation coefficient can produce the signal that contains multi-false-targets information, and the two false targets are simultaneously obtained successfully in simulation.
