| 摘 要： | 根据无人机下行遥测链路的抗干扰技术，详细分析了无人机下行遥测链路的工作原理，提出了三种干扰方式。研究了宽带噪声干扰、单音干扰和脉冲干扰对无人机下行遥测链路干扰效能，给出了误码率计算模型。最后对三种干扰方式的干扰效能进行了仿真和比较，仿真结果显示在不同干信比的情况下，不同干扰方式的干扰效能也不相同。

Evaluation and Simulation for Efficiency of UAV Downlink in P resence of Jamming |
| |
| Abstract: | According to anti?jamming techniques of UAV downlink, working principle of UAV downlink system is analyzed and three types of jamming are given. The jamming effectiveness of BBN jamming, single?tone jamming and pulse jamming to downlink system are analyzed, and the computational model of BER is given. The jamming effectiveness of three jamming methods are simulated and compared, and the simulation results show that the anti?jamming effectiveness of different jamming methods is different by different jamming?signal ratio. |
