摘　　要：以伪码调相引信的启动概率作为衡量标准,研究了射频噪声干扰对该引信的干扰效果.通过建立伪码调相引信启动概率分析模型,从理论上推导出在瞄准式射频噪声干扰下伪码调相引信的启动概率,仿真分析了影响引信启动概率的因素,仿真结果表明,对伪码调相引信的干扰效果除了受到达引信接收机的干信比、干扰带宽等来自干扰方的影响因素影响外,还受到引信码元宽度、码长、接收机带宽、多普勒频率等来自引信自身因素的影响.理论和实际证明,用伪码调相引信的启动概率评估其干扰效果切实可行,可以将其应用于工程实际.Under radio frequency（RF） noise jamming,jamming effect of pseudo-random binary-phase-coded fuze（PRBPCF） is researched based on the criterion of its starting probability.Analysis model of starting probability is set up,the starting probability of the PRBPCF is deduced under RF noise jamming,and the factors influencing the starting probability are discussed.The simulation results show that jamming effect of the PRBPCF is affected not only by jamming to signal ratio（JSR） of reaching receiver and interference bandwidth,but so by pseudo-random code period,code-element width,receiver bandwidth and doppler frequency.Theory and practice prove that starting probability is practicable to be used to evaluate jamming effect of the PRBPCF,and can also be applied to engineering practice.
