Abstract
Interrupted-sampling repeater jamming (ISRJ) is coherent with transmitted signal by intercepting partially and forwarding transmitted signal and poses a huge threat to radar because it is hard to suppress. This paper focuses on the ISRJ suppression by the difference in statistical domain. By deducing the mathematical expression of auto-correlation and cyclic frequency based on modeling echo signal, the difference in statistical domain between target echo signal with ISRJ is shown and used to construct Frequency-Shift (FRESH) filter. The FRESH filter is used to suppress the ISRJ-based false targets. What’s more, the results of FRESH filter is analyzed when the different parameters of ISRJ are choosed. The simulation results demonstrate the applicability of FRESH filter when it is used to suppress ISRJ.
