北斗导航模块抗干扰技术研究

近年来,北斗卫星导航定位系统在无人驾驶、无人机应用、车联网等方面有着越来越重要的作用。但随着电磁环境的日趋复杂,已经严重影响到北斗导航系统的正常使用。因此,基于北斗导航模块抗干扰技术的研究变得尤为重要。本文分析了未来交通领域抗干扰导航技术的需求以及主流的导航抗干扰技术,设计了小型化导航模块,研究了基于频空时域的级联干扰抑制算法,并针对典型干扰场景进行仿真。结果显示,本文设计的北斗小型化导航模块对于窄带干扰具有良好的抑制作用。

Research on Anti-Interference Technology of Beidou Navigation Module

In recent years,the BeiDou Navigation Satellite System(BDS)has been playing an increasingly important role in the driverless vehicles,unmanned air vehicles and internet of vehicles.However,with the increasingly complex electromagnetic environment,the normal use of the BDS has been seriously affected.Therefore,the research of anti-interference technology based on BDS becomes particularly significant.This article analyzes the demand of anti-interference technology and the mainstream anti-interference technology in the future traffic field,designs a miniaturized navigation module,studies the cascade interference suppression algorithm based on frequency-space time domain,and conducts simulation for typical interference scenes.The results show that the Beidou miniaturized navigation module designed in this article has a good inhibitory effect on narrowband interference.
