Anti-Intermittent Sampling Repeater Jamming Method Based on LFM Segmented Pulse Compression
-
摘要: 得益于数字储频技术的快速发展，间歇采样转发干扰(ISRJ)得到广泛应用，现有抗干扰方法尚无法有效对抗此种干扰。在深入研究ISRJ的基础上，针对其时域采样不连续的特点，该文提出一种基于LFM分段脉冲压缩的抗间歇采样干扰方法。该方法利用LFM分段信号之间的正交性，结合掩护波形的思想，通过窄带滤波器组对干扰和目标进行分选，然后剔除干扰，最后在脉内和脉间进行积累。理论分析和仿真结果表明，分段脉冲压缩方法能有效对抗多干扰机情况下不同样式的间歇采样干扰组合。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.
