摘要
在无人机数据链系统中,"信干比"是评判抗干扰是否有效的重要指标。该文基于信干比方程,从发射功率、天线增益、处理增益、信道编码四个方面分析了无人机数据链抗干扰的能力。并取定信干比临界值k,分析了无人机数据链的抗干扰的有效区域。
In UAV dota link system, SIR could be used as index to evaluate its anti-jamming effectiveness. Transmit power, antenna gain, processing gain and channel code are analysed to evaluate the anti-jamming capability of UAV data-link, and the anti-jamming coverage is reckoned with a given SIR
