摘要
现代战场复杂电磁环境严重威胁无线电引信战技性能的发挥。为了提出复杂电磁环境中降低无线电引信意外发火概率的防护对策,在简要介绍了实验装置与方法的基础上,研究了无线电引信的等幅正弦波辐照效应。确定了天线及弹体是造成引信意外发火的主要能量耦合通道,引信意外发火及作用机理是:引信天线及弹体接收正弦波信号,使引信高频电路工作状态发生变化,引信检波电压波动,最终导致引信意外发火。
Nowadays the increase of radio transmitters and radars powers leads to deterioration of evironment. Radio fuze is susceptible to electromagnetic interference. In order to propose of reducing radio fuze accidental explosion in complicated electromagnetism circumintroducing experiment equipment and method, the irradiation effects of invariable amto radio fuze is studied. The coupling entryways of sine wave to radio fuze are the antenna and projectile. The effecting mechanism is that the energy of sine wave couples to radio fuze via the antenna and projectile changes the working state of high frequency circuitry, causes the fluctuation of demodulation voltage and results in the accidental explosion of radio fuze.
