摘要
研究压制性噪声调频干扰对PRCPM-SFM复合调制脉冲串引信的干扰效果.建立了复合引信干扰效果分析模型,推导了该复合引信相关器输出信号在压制性噪声调频干扰下总的信干比增益,提出了以该信干比增益为评估指标的压制性噪声调频干扰效果评估方法,分析讨论了影响干扰效果的几个因素.结果表明,合理利用这些因素,可以有效地提高压制性噪声调频干扰对PRCPM-SFM复合调制脉冲串引信的干扰效果.
The jamming effect of the suppressing noise frequency modulation（NFM） jamming on the pseudo-ran- dom code phase modulation and sine FM（PRCPM-SFM）combined pulse train fuze was investigated. Firstly, an analy- sis model of the jamming effect for the combined fuze was set up. Secondly, the overall signal to jamming ratio （SJR） gain of the correlator output signal was reduced under the NFM jamming. Thirdly, the valuation method of the sup- pressing NFM jamming effect was derived in terms of the overall SJR gain. Finally, the factors influencing the jamming effect were discussed. The result shows that the jamming effect of PRCPM-SFM combined pulse train fuze under the suppressing NFM jamming can be improved effectively by utilizing these factors reasonably.
