A Method for Synthesizing Multi-false-targets Signal for Countering Stepped-Frequency ISAR

To realize multiple false targets deception jamming against stepped-frequency ISAR, a method of synthesizing multi-false-targets signal for countering stepped-frequency ISAR is proposed, and the scheme of the image synthesizer to produce multi-false-targets signal against stepped-frequency ISAR is given in this paper. The multi-false-targets signal synthesis theory and system architecture of the image synthesizer is firstly described in detail, furthermore, it is illuminated using the synthesis process of two and three false targets. Then, the simulations to synthesize multiple false targets have been done, and the multiple false targets deception jamming against stepped-frequency is accomplished. The simulation results show that multiple false targets are produced successfully, and this method is effective and feasible.
