Abstract
An anti-jamming method for M-sequence pseudo-random code phase-modulation and pulse Doppler combined fuze is proposed to solve the less selectable range and easy crack of pseudo-random sequence of m-sequence pseudo-random code phase-modulation and pulse Doppler combined fuze. The M-sequence pseudo-random code phase modulation and pulse Doppler combined fuze is designed based on the characteristics of M-sequence nonlinearity, which is complex in structure, huge number and difficult to be intercepted and reconstructed. The response expressions of each level in the detection process of fuze are derived theoretically, and the anti-jamming performance of M-sequence pseudo-code phase-modulated pulse Doppler combined fuze is quantitatively calculated by taking the processing gain as an index. The theoretical calculated and experimental results show that the M-sequence pseudo-random code phase-modulation and pulse Doppler combined fuze can further improve its anti-active jamming ability compared with m-sequence.
