针对无人机防御的卫星导航干扰方法研究

Research on jamming methods of satellite navigation and positioning system in UAV defense

针对日益增多的恶性无人机“黑飞”现象,并考虑到其卫星导航终端会装载多阵元自适应调零抗干扰天线以提高导航资源使用能力,分析了采用卫星导航干扰进行无人机防御的优点,探索出一种针对无人机防御的卫星导航干扰方法.阐述从单干扰源到多干扰源的导航干扰实施策略,并给出了评估指标.本文研究有助于帮助防护人员准确探索有效防御边界,判断薄弱区域,优化干扰源部署策略,提高防护效率.同时,开发了一款防御效果评估软件,其可呈现防御态势,使得防御效果显示更加直观.

In view of the increasingly vicious UAV“black flight”phenomenon,and considering that its satellite navigation terminal will be loaded with multi-array adaptive zeroing anti-jamming antenna to improve the use of navigation resources,the advantages of using satellite navigation jamming for UAV defense are analyzed,and a satellite navigation jamming method for UAV defense is explored.The implementation strategy of navigation jamming from single interference source to multi-interference source is described,and the evaluation index is given.It helps protection personnel to accurately explore effective defense boundaries,determine weak areas,optimize interference source deployment strategies,and improve protection efficiency.A defense effect evaluation software is developed,which can present the defense situation and make the defense effect display more intuitive.
