超宽带电磁脉冲对无线电引信辐照效应研究

为了研究无线电引信在强电磁环境下的安全性和可靠性,利用频带很宽的超宽带电磁脉冲（UWB）源对某型无线电引信系统进行了辐照实验。对不同姿态的无线电引信系统的UWB辐照试验表明,当无线电引信系统的轴线方向与超宽带辐射场极化方向一致时,电磁能量耦合最强,最易于受到超宽带电磁辐射场的干扰;在无线电引信系统不加电情况下,UWB辐照基本不会使无线电引信起爆,也不会对其产生明显影响;但是较强的UWB辐射场会使处于加电工作状态下无线电引信意外起爆,但经过辐照后整个无线电引信系统内在性能参数不会产生明显变化。

Research on Radiation Effects of Ultra-Wide Band Electromagnetic Pulse on Radio Fuze

In order to research the security and reliability of radio fuze under the strong electromagnetic pulse environment,the EMP radiation test of a type of radio fuze has been done by use of UWB EMP generator. The radiation test of UWB EMP on the radio fuze of different attitudes was conducted, and the results show that the fuze is most easily interfered with and the electromagnetic energy coupling is strongest while the axial direction of the radio fuze system and the polarized direction of UWB EMP are in concord ance. The test indicates that the power-off radio fuze cannot be exploded or be influenced by the radiation of UWB EMP. However the stronger UWB EMP may initiate the radio fuze in the working state unexpectedly,and the performance of the radio fuze system has no obvious change after being radiated by UWB EMP.
