摘　　要：近年来,无人机技术不断进步与完善,在军民领域都得到了广泛应用。然而,频频发生且影响广泛的"黑飞"与滥用现象,引发了对低空无人机进行反制与干扰的热点研究。本文围绕低空民用小型无人机,结合目前较为成熟的无人机通信链路干扰技术,深入研究了切断无人机通信链路后MIMU/GPS组合的GPS定位诱骗干扰问题,通过延迟转发,人为改变可见卫星到无人机的伪距值诱使无人机朝着错误的位置飞行,研究目标是希望仅通过改变较少卫星的伪距,实现在MIMU独立定位误差范围内较大拉偏定位误差,从而达到有效诱骗,缩短诱骗引导其到达预定坐标的时间。该技术可组合无人机通信链路干扰技术构建对于低空民用小型无人机的经济、简单有效的反无人机系统。In recent years,unmanned aerial vehicle ( UAV) technology has been continuously improved and applied in the military and civilian fields.However,the frequent and widespread'black flight'and abuse phenomenon has triggered the research on countermeasure and interference of low-altitude UAV.Around low level civil small unmanned aircraft,this paper combine the UAV communication link interference of a mature technology,further study of the cut after the UAV communication link of MIMU/GPS integrated GPS decoy jamming problem,through delay forwarding,artificial drone pseudorange values change visible satellites to lure flying unmanned aerial vehicle ( UAV) moving in the wrong position,the research goal is to hope that only by changing the small satellite pseudorange,implementation within the scope of MIMU independent positioning error larger partial positioning error,so as to achieve effective lure,shorten the decoy to guide its time of arrival in scheduled coordinates.This technology can be combined with uav communication link jamming technology to build an economical,simple and effective anti- UAV system for low-altitude civil small UAV.
