摘要
研究压制性噪声调频干扰对伪码调相引信的干扰效果.建立了接收机干扰效果仿真模型,分析了压制性噪声调频干扰对伪码调相引信干扰的机理,提出了基于相关器输出值过门限概率大小的压制性干扰效果评估方法,仿真分析了影响干扰效果的几个主要因素.仿真结果表明,采用窄带瞄准式干扰,增加接收机输入干信比,减小干扰带宽,提高载频瞄准度,可以增强干扰效果.
Jamming effect of suppressing noise frequency modulation jamming of pseudo-random code phase modulation fuze was researched.The principle of pseudo-random code phase modulation fuze（PRCPMF）being jammed was analyzed according to the receiver simulation model,the valuation method of suppressing jamming effect were put forward based on the probability of correlator output value excceding comparison threshold level,and factors influencing jamming effect were discussed.The simulation result shown the jamming effect of pseudo-random code phase modulation fuze can be enhanced by these measures,such as adopting narrow-bandwidth spot jamming,increasing jamming to signal ratio of the receiver,reducing the interference bandwidth,and improving targeting carrier frequency degree.
