摘要
无线电引信对抗是机载自卫电子战系统的重要组成部分,但由于导弹引信开机时间短、辐射功率低等特殊性,目前国内外尚未见有对来袭导弹引信进行明确侦察引导的干扰对抗。为论证可行性,采用从空间和时间两个角度,对引信工作过程、弹目交会及引战配合过程进行分析,分别计算引信信号可侦测时间及可探测距离,得出引信可侦察时间与可干扰时间并不重合,在一定条件下引信信号在开机后被侦察截获并用于引导干扰是可行的。在目前综合一体化电子战思想架构下,基于当前的硬件技术水平,基本上能在限定的时间内完成对数据的处理,实现对引信信号的高截获和快处理。
The radar fuse countermeasures were one of the important tasks of airborne self-defense electronic warfare system.However,there are not yet any effective countermeasures to the incoming missile fuse at present both at home and abroad since the missile fuse has short working time and low radiation power.To study the feasibility of fuse signal detection and countermeasure,the working processes of the fuse and fuse-warhead coordination were analyzed,the time duration and the distance when the fuse signal can be detected were calculated out.The result showed that：1） the time when the fuse signal can be detected is not as the same as when it can be jammed effectively;and 2） it is feasible to detect and intercept the fuse signal under special conditions when the fuse begins to work.Under the current integrated electronic warfare framework and with the modern technologies,it is possible to implement data processing within limited time and realize higher interception probability and rapid processing of fuse signal.
