基于M码的GPS干扰技术

GPS Jamming Techniques Based on M Code

由于拦阻式干扰对功率需求过大,会带来硬件实现及干扰平台生存问题,同时全球定位系统(GPS)抗干扰技术(如功率倒置阵算法、天线自适应调零技术、组合导航技术等)的使用,会极大降低传统干扰技术的干扰效能。为解决上述问题,从技术角度出发,针对GPS干扰和抗干扰技术特点,选择点频干扰、同速率伪码干扰和相关伪码干扰三种具有代表性的干扰样式进行理论分析及干扰效能评估。

Because the reqired power is too large while using barrage jamming,which will bring about the questions of hardware realization and jamming platform survival,at the same time the usage of global positioning system（GPS）anti-jamming techniques（such as power inversion array algorithm,antenna adaptive zero setting technique,combination navigation technique,etc.）will greatly decrease the jamming efficiency of traditional jamming techniques.For solving the above problems,in the technical aspect,aiming at the technique characteristics of GPS jamming and antijamming,this paper chooses three kinds of representative jamming modes such as the spot frequency jamming,pseudocode jamming with the same-velocity and relevant pseudocode jamming to perform principle analysis and jamming efficiency evaluation.
