Abstract

Interrupted-Sampling Repeater Jamming (ISRJ), as a typical selfscreening jamming pattern, achieves effective interference against radar devices by generating multiple false target echo signals to mask the true target echo signals that need protection. According to the principle of jamming generation, it is known that the sampling duration and the repeater number of sampling segment are key parameters that determine the effectiveness of the jamming. In this study, through theoretical derivation and simulation verification, the impact of changes in the sampling duration and the repeater number of sampling segment on the interference effect was analyzed in-depth by adopting pulse compression processing on the signal. The results show that the sampling duration can affect the distribution of false target groups, and the repeater number of sampling segment can influence the spacing between primary and secondary false targets within the groups. By setting appropriate values, the false targets generated through Interrupted-Sampling Repeater Jamming can protect the true targets.
