数据链智能抗干扰设计与实现

Design and Implementation of Intelligent Anti-Interference for Data Link

分析数据链通信在超高音速无人飞行器上的应用场景和面临的问题,列出当下数据链通信中主流的干扰样式类别、发展趋势和抗干扰的手段。详细描述智能抗干扰引擎的设计技术方案,分别从总体方案、宽带频谱感知模块、干扰信号识别模块、抗干扰决策模块4个方面对智能抗干扰引擎的设计进行论述。对于主要关键技术的技术途径进行分析,并对所采用方法的性能进行仿真测试,对仿真测试的结果进行对比和分析。仿真测试结果可以证明所采用的方法能够达到预期目标,但仍存在一定的局限性,对实际工程和实用效果还有待进一步验证。

The application scenarios and problems faced by data link communication on hypersonic unmanned aerial vehicles were introduced, and the mainstream jamming style categories, development trends and anti-jamming methods in current data link communication were listed. The design and technical scheme of the intelligent anti-jamming engine was described in detail, and the design of the intelligent anti-jamming engine was discussed from four aspects: the overall scheme, the broadband spectrum perception module, the interference signal recognition module, and the anti-interference decision-making module. The technical approaches of the main key technologies were introduced, the performance of the adopted methods was simulated and tested. The results of the simulation tests were compared and analyzed, and the simulation tests could proved that the methods used could achieved the expected goals, but there were still certain limitations, and the actual engineering and practical ef fects need to be further verified.
