摘  要:针对无线电引信电磁防护性能试验评估的技术需求,提出了连续波电磁辐射效应试验方法和操作程序.试验研究了某型分米波无线电引信的单频、扫频和调幅电磁辐射效应,确定了不同调制方式下的临界起爆场强变化规律.结果发现:单频电磁辐射导致无线电引信起爆的场强存在上限值;单频、扫频、调幅电磁辐射导致无线电引信意外起爆的能力依次增强,最小临界起爆场强仅为0.38V/m,以此为基础,分析了连续波电磁辐射对无线电引信的干扰机理,提出了无线电引信电磁防护加固方法和高效干扰方法.In order to evaluate the electromagnetic protection performance of radio fuze, an experimental method and operation process were proposed for continuous wave electromagnetic radiation effect. The radiation effect was studied experimentally for a kind of decimeter-wave radio fuze in different radiation ways, including single-frequency radiation, sweep frequency radiation and amplitude-modulated radiation. The change laws of the critical firing field were obtained for the fuze in three radiation ways, and the interference mechanisms were also analyzed. The results show that, there is an upper limit in the firing field of radio fuze induced by single-frequency electromagnetic radiation, and a sudden firing possibility of the radio fuze can enhance by single-frequency radiation, sweep frequency radiation and amplitude-modulated radiation in turn, the least critical firing field is 0.38 V/m merely. Based on the above results and the interference mechanism of continuous wave electromagnetic radiation, an electromagnetic reinforcement method for radio fuze and an efficient interference method to radio fuze are put forward.
