摘要/Abstract

摘要： 针对基于m序列伪码调相的脉冲多普勒引信伪随机序列可选择范围少、易被破解等问题，提出基于M序列伪码调相的脉冲多普勒引信抗干扰方法。利用M序列非线性结构复杂、数量巨大而不易被截获和重构的特性，设计了基于M序列的伪码调相脉冲多普勒引信；理论推导了引信探测过程中的各级响应表达式，并以处理增益为指标对M序列伪码调相脉冲多普勒引信抗干扰性能进行定量计算。理论计算和实验研究结果表明，与m序列相比，基于M序列的伪码调相脉冲多普勒引信能够进一步提高其抗有源干扰的能力。

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.
