| Abstract: | With the increasing complexity of electromagnetic environment and the continuous progress of interference technology,various applications of global navigation satellite system(GNSS) are severely hindered.In strong interference environment,the spread spectrum gain is not enough to effectively suppress interference,so various anti-interference measures are needed.In this paper,the research results of GNSS anti-interference technology are reviewed.The anti-interference technology of GNSS is classified,and the current states and progress of different anti-jamming technologies are outlined.The GNSS interference sources and interference types are summarized,and the corresponding anti-interference technology is given for different interference types.Then,the performance of several common adaptive algorithms are compared and analyzed.Finally,the future development direction of GNSS anti-jamming technology is pointed out. |
| Keywords: | GNSS anti-jamming technology adaptive algorithm |
