摘要
在无线电引信中,多普勒无线电引信由于无法提供距离信息比较容易受到干扰;针对现代战争中日益恶化的电磁环境对引信的干扰问题,以Ansoft软件为仿真平台,建立导弹脉冲多普勒引信天线的物理结构模型和电路模型,通过计算机仿真分析了耦合的电磁场以及电磁波能量对引信关键器件的影响情况。结果表明,所研究的HPM由于持续时间短,无法达到压制干扰的目的。由于限幅器的作用,HPM脉冲进入引信执行级的能量也很低,且不满足多普勒频率的要求,无法使引信误启动。
In radio fuze,the Doppler radio fuze can be easily disturbed as it can't provide the distance information.With the worse electromagnetic environment for fuze in modern warfare,the constitution and circuit models of missile radio fuze's antenna were set up with Ansoft software.The effects of coupled electromagnetic field and electromagnetic energy to key devices of fuze were simulated.The results shows that as the duration of HPM was short,the extrude and interfere can't be realized.As the effect of the limiter,the energy of HPM impulse into the fuze executive devices was low.The requiry of Doppler frequency can't be satisfied and there is no mis-starting of fuze.
