In order to counter PD fuze with excellent anti-jamming performance, the basic working principle was analyzed, on the basis of the analysis, essential conditions of jamming PD fuze were determined. Based on the essential conditions, the circular-repeater jamming technique based on digital radio frequency memory (DRFM) was presented in order to jam PD fuze. In order to verify effectiveness of the approach, simulation was designed. The results of simulation demonstrate that the jamming signal based on this technique could satisfy the essential conditions, and the circular-repeater jamming technique based on DRFM countering PD fuze is valid.
