摘要
为了研究全球定位系统(Global Positioning System,GPS)转发欺骗式干扰中的干扰源部署问题,文中从真实点邻域被映射情况的角度出发,以四站和单站转发为例,推导了真实点邻域被映射情况以及在该邻域内干扰对接收机钟差影响的算法。得到了具有较好映射关系时需满足的条件,提出了一种易于实现的GPS欺骗式干扰源部署方法。仿真结果验证了推导结论与所提方法的正确性,为GPS转发欺骗式干扰的辅助决策提供参考。
In order to research deployment of jammer in GPS repeater deception,mapping situation of real locus＇ neighborhood is taken as the point of view in this paper,four transmitters jamming and single transmitter jamming are taken as examples,the algorithm of mapping of the locus＇ neighborhood and the receiver＇s clock off-sets is presented. The condition which has good mapping relationship is given,a deployment method of jammer in GPS repeater deception jamming which is easy to be realized is put forward.The exactitude of the conclusion and the method is proved by the simulation,reference of auxiliary decision in GPS repeater deception jamming is provided.
