Abstract

Abstract

Benefiting from the rapid development of digital frequency storage technology, the Intermittent Sampling Repeater Jamming(ISRJ) is widely used. Existing radar anti-jamming means are hard to against this jamming effectively. Based on the analysis of the principles of the ISRJ, for the discontinuities of ISRJ in time domain, an anti-ISRJ method based on LFM segmented pulse compression is proposed. This method utilizes the orthogonality between LFM segmented signals, combines with cover waveform concept, distinguishes jamming and target through narrow band filter group, then suppresses jamming, finally accumulates signals in intra-pulse and inter-pulse. Theoretical analysis and experimental results show the anti-ISRJ method can effectively resist the intermittent sampling interference which combines with different styles of multiple jammers.
