【摘要】：GPS(全球定位导航系统)天线滤波和极化抗干扰技术,使得宽带阻塞式干扰的效能急剧下降。为了解决这个问题,提出了一种采用伪码瞄准式干扰方案。方案能够对GPS信号进行干扰,并且干扰性能得到提升。分析了伪码瞄准式干扰原理和评估标准,对GPS伪码瞄准式干扰机进行了设计,分别包括伪码干扰源模块设计和载波模块设计,并给出了个电路的原理和硬件实现。对GPS接收机的载噪比进行了测试,实验结果表明伪码瞄准式干扰,载噪比降低,具有干扰功率集中的优点。相比宽带阻塞式干扰,性能得到提升。
[Abstract]:GPS (Global Positioning system) antenna filtering and polarization jamming technology make the wideband blocking jamming performance decline dramatically. In order to solve this problem, a pseudo-code aiming interference scheme is proposed. The scheme can interfere with GPS signal and improve the jamming performance. This paper analyzes the principle and evaluation standard of pseudo-code aiming jamming, designs the GPS pseudo-code aiming jamming machine, including the design of pseudo-code interference source module and carrier module, and gives the principle and hardware implementation of a circuit. The GPS receiver's carrier to noise ratio is tested. The experimental results show that the pseudo code aiming interference and the lower carrier noise ratio have the advantages of concentrated interference power. Compared with wideband blocking interference, the performance is improved.
