Abstract： Interrupted sampling repeater jamming （ISRJ） poses a significant threat to coherent radar systems by intercepting，storing，modulating，and retransmiting enemy radar signals，thereby generating multiple false target peaks after matched filtering.Based on an analysis of the typical mechanisms of intermittnt forwarding jamming，the radar side has developed corresponding anti-jamming techniques at both the receiving and transmiting ends，effectively suppressing this type of jamming. In response，the jamming side has proposed various improved strategies to enhance the effectiveness of intermittent forwarding jamming. However，few studies have explored how these improved jamming methods perform against radar anti-jamming techniques.To address this gap，the existing literature and summarizes representative improvements in intermitent forwarding jamming are reviewed firstly， along with typical radar anti-jamming methods. Subsequently，experiments are conducted to analyze the effectiveness of these improved jamming techniques in countering radar anti-jamming measures. Simulation results demonstrate that the enhanced ISRJ methods can efectively confront advanced radar anti-jamming strategies，thereby significantly improving the overalljamming performance.
