N2 - Both digital radio frequency memory (DRFM)-based interrupted-sampling repeater jamming (ISRJ) and full pulse forwarding jamming (FPFJ) utilize the coherence of radar signals to form multiple false targets by sampling, storing, processing and forwarding the received signals. In order to improve the radar's ability to restrain forwarding false target jamming, this paper proposes a forwarding false target jamming suppression method based on the characteristics of the peak distribution of high-resolution range profiles (HRRP). False targets have a distribution pattern of approximately equal intervals during forwarding, while the distribution of targets has no regularity. Therefore, a peak interval threshold is designed to achieve false target jamming recognition and suppression. Finally, the effectiveness of the method is validated through simulations.
