【摘要】:GPS(全球定位導(dǎo)航系統(tǒng))天線濾波和極化抗干擾技術(shù),使得寬帶阻塞式干擾的效能急劇下降。為了解決這個問題,提出了一種采用偽碼瞄準(zhǔn)式干擾方案。方案能夠?qū)PS信號進行干擾,并且干擾性能得到提升。分析了偽碼瞄準(zhǔn)式干擾原理和評估標(biāo)準(zhǔn),對GPS偽碼瞄準(zhǔn)式干擾機進行了設(shè)計,分別包括偽碼干擾源模塊設(shè)計和載波模塊設(shè)計,并給出了個電路的原理和硬件實現(xiàn)。對GPS接收機的載噪比進行了測試,實驗結(jié)果表明偽碼瞄準(zhǔn)式干擾,載噪比降低,具有干擾功率集中的優(yōu)點。相比寬帶阻塞式干擾,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.
