| 摘 要： | 随着GPS在装备中的广泛应用,对GPS干扰技术的研究也具有越来越重要的意义。通过研究GPS信号调制方式,特别是BOC调制的特点,建立了GPS信号仿真数学模型,利用欺骗干扰和压制干扰模型,对各种干扰技术进行了建模和仿真,得到了时域、频域干扰曲线和信干比与误码率的关系曲线,从而实现了干扰性能的评估。

| Abstract: | With the application of GPS equipment in foreign military, the research of GPS signal jamming technology becomes more and more significant. Based on analyzing modulation method of GPS signal, especially the features of the BOC modulation method, mathematical models are built to emulate GPS signal. Model building and emulation of all jamming technologies are finished with the deception jamming and the barrage jamming models, related curves of the jamming, SIR and BER are output in both time field and frequency field to assess the capability of all the jamming technologies. |
