摘　　要：文中研究影响伪码体制引信抗噪声调频干扰性能的主要因素。首先介绍了伪码体制引信的工作原理;然后在噪声调频干扰模式下,推导了伪码体制引信相关接收机信干比增益,研究了多普勒频率对其的影响,给出了伪码体制引信在接收机带宽等于发射信号带宽下抗噪声调频干扰的统一信干比增益表达式;最后分析了伪码体制引信本身的特征参数等对其抗噪声调频干扰性能的影响。为提高伪码体制引信的抗干扰性能和有效干扰这种体制引信提供了重要理论依据。The major factors affecting the anti-jamming performance of pseudo-random coded fuzes are analyzed in this paper.Firstly the principle of pseudo-random coded fuzes was introduced.Secondly on this basis,its signal to jamming ratio(SJR)of receiver with Doppler frequency were deduced in the environment of noise FM jamming,then unified representation is put forward.From the SJR its working frequency,pulse width,pseudo-random code period and other factors affect its anti-noise frequency modulation(FM)jamming performance.It provides the important theoretic foundation for the improvement on anti-noise FM jamming performance of pseudo-random coded fuzes and jamming them effectively.
