Research on predictive deception jamming technology of pulse system pseudo-code phase modulation fuze

Pulse system pseudo-code phase modulation fuze is a typical compound modulation radio fuze. The fuze uses narrow pulse sampling, range gating, pseudo-random code correlation detection technology, which has a strong range resolution ability. In this paper, a predictive deception jamming technology is proposed to solve the problem that the jamming signal of the conventional fuze lags behind the target echo. The pseudo-code sequence of the fuze signal is obtained by reconnaissance, and the model parameters are estimated by combining the pseudo-code M sequence model. A jamming sequence is generated whose phase lead fuze signal during pulse duration. The fuze signal is jammed in time domain, frequency domain, modulation domain and power domain, and the jamming signal can enter the distance gate of the fuze signal in advance, so that the fuze starts in advance. The simulation results show that the jamming technology can counter the pulse system pseudo-code phase modulation fuze and has good jamming effect.
