摘要:

舷外有源诱饵是应对主动雷达制导反舰导弹的重要干扰手段之一, 但在使用上, 其存在干扰响应时间短且干扰态势要求高的时空局限性。针对这一问题, 本文基于无人艇平台, 提出了多舷外有源诱饵组合干扰样式, 通过无人化与集群化提升舷外有源诱饵的作战效能。首先, 根据反舰导弹单脉冲主动雷达导引头的测角原理, 从信号层面推导了多诱饵干扰下的角度响应。其次, 从态势层面, 分析了多诱饵组合干扰的有效性临界条件; 接着, 结合信号与态势, 提出了多诱饵组合干扰评估方法。最后, 通过仿真与数值分析, 验证了多诱饵对干扰效果的提升作用以及评估方法的可行性, 为舷外有源诱饵的集群化干扰提供了理论支撑。

Abstract:

The offboard active decoy is one of the important jamming methods to confront active radar guided anti-ship missiles. However, it has space-time limitations of short jamming response time but high jamming situation requirements. To solve this problem, based on the unmanned boat platorm, a combined jamming type of multiple offboard active decoy is proposed to enhance the jamming effectiveness through unmanned clustering in this paper. Firstly, based on the angle measurement principle of the monopulse radar on the anti-ship missile seeker, this paper derived the indicated angle of the radar seeker under the multi-decoy jamming from the signal level. Secondly, the critical jamming conditions for the effective jamming effect of multiple combined decoys are analyzed at the situational level. Then, combining the jamming signal and the critical situation, we propose a probabilistic inference based jamming effectiveness assessment method for multiple offboard active decoys. Finally, the improvement of multiple decoys on jamming effect and the feasibility of the assessment method are verified through simulation and numerical analysis, which provides theoretical support for clustered jamming of offboard active decoys.

Key words: multiple offboard active decoys, unmanned surface vehicle, angle deception, combined jamming, interference effectiveness assessment
