摘　　要：进行大型无人机电子通讯信号抗干扰方法研究与仿真,通过GPS系统确定信号的来源与方向定位,利用GPS定位信息准确计算最小均方、最大信噪比与最小方差,依据选择最优准则,实现对复杂抗干扰信号的削弱与排除。仿真实验表明,针对干扰信号,该种自适应滤波抗干扰算法具有较强的抑制与削弱能力,并扩大了干扰信号搜索范围,有效抵抗复杂的干扰信号,与常规抗干扰算法比较更为可靠,为无人机电子通讯抗干扰方法研究提供更好的保障。Large uavs electronic communication signal anti-jamming method research and simulation, through the GPS posi-tioning system to determine the signal source and direction, using GPS positioning information to calculate the minimum mean square accurately, and maximum signal-to-noise ratio and minimum variance, on the basis of choosing the optimal criterion, implementation of complex interference signals and ruled out. Simulation results show that, in view of the interfer-ence signal, this kind of adaptive filter anti-jamming algorithm has strong inhibition and weaken the ability, and expand the search range of the interference signal, effective against complex jamming signal, compared with conventional anti-jam-ming algorithm is more reliable, for unmanned aerial vehicle (uav) electronic communication anti-jamming method re-search for better security.
