A Smart Multiple False Target Jamming Technique

The generation of coherent false target is the key technique of deceptive jamming. According to the technology of modern radar, the requirement of jamming technique is much higher. First, the technique of interrupted-sampling repeater jamming is introduced. And then a new method of generating numerous coherent multiple false target by modulating the spectrum of signal is proposed. The figure of structure and the form of jamming signal are presented. Based on this, a new jamming technique by combining the technique of interrupted sampling repeater jamming with spectrum modulation is generated. Compared with the technique of interrupted-sampling repeater jamming, the feasibility and advantage of this new technique is verified with the simulation results.
