doi:10.3969/j.issn.1000-1093.2018.06.007

Abstract

Abstract: The working principle of pseudo-random code phase-modulation and pulse Doppler fuze with excellent anti-jamming capability is analyzed. On the basis of the analysis, a code reconstruction-based jamming signal method is proposed, and the jamming effect of the proposed method is analyzed theoretically. Third-order correlation function is used to estimate the pseudo-random code sequence, and the signal of jamming the fuze is reconstructed based on the estimated pseudo-random code sequence. The simulated and experimental results demonstrate that the proposed method has deceptive jamming effect on the fuze. The proposed method is more efficient than the traditional jamming method. Key

Key words: pulseDopplercombinedfuze, pseudo-randomcodephase-modulation, codereconstruction, pseudo-randomcodeestimation, three-ordercorrelationfunction
