| 摘要: |
| 针对卫星通信干扰排查中信号难捕捉、源难定位、成因难分析、难验证的瓶颈，提出了基于数字孪生的全流程闭环方案。构建了物理感知、虚拟孪生与智能决策三元融合架构，并融合了弱特征提取、多源数据融合定位、因果追溯及虚拟预验证4项关键技术，实现了从被动响应到主动精准决策的转变。实验表明，该方案在典型场景下干扰识别准确率最高达94.8%，静态定位精度达百米级，处置抑制率最高达89.62%；在极端复杂场景下仍满足应急要求，性能显著优于传统方法。 |

| Abstract: |
| In response to the bottlenecks in satellite communication interference troubleshooting，shuch as the difficulties in signal detection，source localization，cause analysis，and effectiveness verification，a full-process closed-loop scheme based on digital twin technology is proposed.A tri-integrated architecture comprising physical perception，virtual twin，and intelligent decision-makingis constructed.It incorporates four key technologies including weak feature extraction，multi-source data fusion localization，causal tracing，and virtual pre-verification，thereby shifting the troubleshooting process from passive response to active and precise decision-making.Experiments demonstrate that the proposed scheme achieves a maximum interference recognition accuracy of 94.8%，a static localization accuracy of hundred-meter level，and a maximum disposal suppression rate of 89.62% under typical scenarios.It still meets emergency requirements in extreme complex scenarios and performs significantly better than traditional methods. |
