摘要/Abstract

摘要： 为了定量分析和表征脉冲多普勒（PD）引信的抗干扰性能，以处理增益为参量，研究了周期调制干扰信号对脉冲多普勒引信的作用效果，明确了脉冲多普勒引信抗干扰性能的影响因素。理论推导了典型周期调制干扰信号作用下，脉冲多普勒引信从接收回波到相关检测这一过程的处理增益，获得了脉冲多普勒引信抗干扰性能与影响因素之间的量化关系，既为脉冲多普勒引信抗干扰设计提供了理论依据，又为脉冲多普勒引信抗干扰性能评估提供了技术支撑。理论推导、仿真和实测结果表明：脉冲多普勒引信抗周期性调幅干扰性能弱于抗周期性调频干扰性能；抗周期调制干扰性能主要受距离门脉冲宽度、多普勒滤波器类型和带宽影响。

Abstract: The jamming effect of periodic modulation signal on pulse Doppler (PD) fuze is studied based on the parameter of processing gain to quantitatively analyze and characterize the anti-jamming performance of PD fuze and obtain the factor that affects the anti-jamming performance of PD fuze. The processing gain of the procedure from echo reception to correlation detection under the interference of typical periodic modulation jamming style is derived. The quantitative relation between the anti-jamming performance of PD fuze and the characteristic parameter that affects the anti-jamming performance is obtained. It provides a theoretical basis for the improvement of interference performance of PD fuze and technical support for the interference performance assessment of PD fuze. Theoretical derivation, simulation and measurement results indicate that the anti-jamming performance of PD fuze to periodic amplitude modulation is worse than its anti-jamming performance to periodic frequency modulation, and the anti-periodic modulation jamming performance mainly depends on range gate pulse width, Doppler filter bandwidth and filter type.

Key words: pulse Doppler (PD) fuze, anti-jamming performance, processing gain, periodical amplitude modulation jamming, periodical frequency modulation jamming
