摘　　要：Interrupted-sampling repeater jamming （ISRJ） is a novel jamming mode for pulse compression radar in principle. In this paper, a jamming approach of applying ISR3 to de-chirping radar is presented. The principles of ISRJ are expounded, and the ways to achieve a train false target for de-chirping radar are analyzed. The characteristics of false target, including time-domain characteristic, frequency-domain characteristic and amplitude characteristic, are described. Based on this, the power requirement for jammer is put forward and the key elements that determine the space distribution location between true and false targets are discussed in detail. At last, simulation results are presented and addressed. This work is beneficial to the jamming design and use of ISRJ.Interrupted-sampling repeater jamming （ISRJ） is a novel jamming mode for pulse compression radar in principle.
