Anti-DRFM-jamming Method Based on Averaging of Range Side Lobes for Hybrid Modulation Radio Fuze

doi:10.3969/j.issn.1000-1093.2020.04.003

Abstract

Abstract: To enhance the anti-digital radio frequency memory (DRFM)-jamming performance of hybrid modulation continuous waveform detectors, the binary phase-coded chirp waveforms which are aperiodic are designed, and an anti-DRFM-jamming method based on averaging of the range side lobes is proposed. The chaotic codes vary with the linear frequency modulation (LFM) period to make the binary phase-coded chirp waveforms be aperiodic, and the range side lobes are used to suppress the influence of the DRFM. The proposed method is proven to be feasible and effective through numerical simulations. Key

Key words: radiofuze, electroniccountermeasure, hybrid-modulation, digitalradiofrequencymemory, rangesidelobe
