| 摘 要： | 无人机在实际飞行过程中，在某些区域总会出现通信误码率较高甚至失锁的现象。通过分析无人机链路的信道特点，利用两径传播模型分析了信号电平衰落的分布和深衰落担度，并用MATLAB对此模型进行了仿真。仿真数据与工程经验数据进行了比较，结果表明此模型能够很好的解释飞行弱区这种现象，也进一步验证了该模型的适用性。

| Abstract: | The phenomenon of high BER, even losing lock always appear in certain areas in practical flight of UAV. The characteristics of UAV link are analyzed, and the distribution of signal level fading and the strength of the deep fading are analyzed with the two-path transmission model which is simulated with MATLAB. The simulated result is compared with the empirical data, the result indicates that the model can well explain the phenomena of deep fading in flight. The applicability of the model is further verified. |
