摘要/Abstract

摘要： 为了有效干扰伪码调相脉冲多普勒引信，提出了基于码元重构的干扰信号设计方法。采用3阶相关函数对伪随机码进行了盲估计，基于估计出的伪随机码重构了引信干扰信号，理论分析了该干扰信号对伪码调相脉冲多普勒引信的干扰效果。仿真和试验结果表明，基于码元重构的干扰方法能够对伪码调相脉冲多普勒引信产生欺骗式干扰效果，与传统干扰信号相比，码元重构干扰具有更高的干扰效率。

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
